A tree ... - The statement points to a natural agency, but the result was manifestly supernatural.

He made ... - The Lord then set before them the fundamental principle of implicit trust, to be shown by obedience. The healing of the water was a symbol of deliverance from physical and spiritual evils.

He cried unto the Lord - Moses was not only their leader, but also their mediator. Of prayer and dependence on the Almighty, the great mass of the Israelites appear to have had little knowledge at this time. Moses, therefore, had much to bear from their weakness, and the merciful Lord was long-suffering.

The Lord showed him a tree - What this tree was we know not: some think that the tree was extremely bitter itself, such as the quassia; and that God acted in this as he generally does, correcting contraries by contraries, which, among the ancient physicians, was a favourite maxim, Clavus clavo expellitur. The Targums of Jonathan and Jerusalem say that, when Moses prayed, "the Word of the Lord showed him the tree ארדפני ardiphney, on which he wrote the great and precious name of (Jehovah), and then threw it into the waters, and the waters thereby became sweet" But what the tree ardiphney was we are not informed.

Many suppose that this tree which healed the bitter waters was symbolical of the cross of our blessed Redeemer, that has been the means of healing infected nature, and through the virtue of which the evils and bitters of life are sweetened, and rendered subservient to the best interests of God's followers. Whatever may be in the metaphor, this is true in fact; and hence the greatest of apostles gloried in the cross of our Lord Jesus Christ, by which the world was crucified to him and he unto the world.

It appears that these waters were sweetened only for that occasion, as Dr. Shaw reports them to be still brackish, which appears to be occasioned by the abundance of natron which prevails in the surrounding soil. Thus we may infer that the natural cause of their bitterness or brackishness was permitted to resume its operations, when the occasion that rendered the change necessary had ceased to exist. Thus Christ simply changed that water into wine which was to be drawn out to be carried to the master of the feast; the rest of the water in the pots remaining as before. As the water of the Nile was so peculiarly excellent, to which they had been long accustomed, they could not easily put up with what was indifferent. See Clarke's note on Exodus 7:18.

There he made for them - Though it is probable that the Israelites are here intended, yet the word לו lo should not be translated for them, but to him, for these statutes were given to Moses that he might deliver them to the people.

There he proved them - נסהו nissahu, he proved Him. By this murmuring of the people he proved Moses, to see, speaking after the manner of men, whether he would be faithful, and, in the midst of the trials to which he was likely to be exposed, whether he would continue to trust in the Lord, and seek all his help from him.

And he cried unto the Lord,.... Or prayed, as all the Targums, that God would appear for them, and relieve them in their distress, or, humanly speaking, they must all perish: happy it is to have a God to go to in time of trouble, whose hand is not shortened that it cannot save, nor his ear heavy that he cannot hear! Moses knew the power of God, and trusted in his faithfulness to make good the promises to him, and the people, that he would bring them to the land he had swore to give them:

and the Lord shewed him a tree, which when he had cast into the waters, the waters were made sweet; what this tree was is not known; if it was in its own nature sweet, as the author of Ecclesiasticus seems to intimate, when he says, in chapter 38:5 "was not the water made sweet with the wood, that its virtue might be known?" Yet a single tree could never of itself sweeten a flow of water, and such a quantity as was sufficient for so large a number of men and cattle; and therefore, be it what it will, it must be owing to a miraculous operation that the waters were made sweet by it: but the Hebrew writers say the tree was bitter itself, and therefore the miracle was the greater: Gorionides (l) says it was wormwood; and both the Targums of Jonathan and Jerusalem call it the bitter tree, Ardiphne, which Cohen de Lara (m) makes to be the same which botanists call Rhododaphne or rose laurel, and which, he says, bears flowers like lilies, which are exceeding bitter, and are poison to cattle; and so says Baal Aruch (n); and much the same has Elias Levita (o): and this agrees well enough with the mystical and spiritual application that may be made of this; whether these bitter waters are considered as an emblem of the bitter curses of the law, for that bitter thing sin, which makes work for bitter repentance; and for which the law writes bitter things against the sinner, which, if not prevented, would issue in the bitterness of death; so that a sensible sinner can have nothing to do with it, nor can it yield him any peace or comfort: but Christ, the tree of life, being made under the law, and immersed in sufferings, the penalty of it, and made a curse, the law is fulfilled, the curse and wrath of God removed, the sinner can look upon it with pleasure and obey it with delight: or whether these may be thought to represent the afflictions of God's people, comparable to water for their multitude, and for their overflowing and overwhelming nature, and to bitter ones, being grievous to the flesh; especially when God hides his face and they are thought to be in wrath: but these are sweetened through the presence of Christ, the shedding abroad of his love in the heart, the gracious promises he makes and applies, and especially through his bitter sufferings and death, and the fruits and effects thereof, which support, refresh, and cheer, see Hebrews 12:2,

there he made a statute and an ordinance: not that he gave them at this time any particular law or precept, whether moral or ceremonial, such as the laws of keeping the sabbath and honouring of parents, which the Targum of Jonathan mentions (p); and to which Jarchi adds that concerning the red heifer: but he gave them a general instruction and order concerning their future behaviour; that if they hearkened to his commandments, and yielded obedience to them, it would be well with them, if not they must expect to be chastised and afflicted by him, as is observed in the following verse, to which this refers:

and there he proved them; the people of Israel; by these waters being first bitter and then sweetened, whereby he gave them a proof and specimen how it would be with them hereafter; that if they behaved ill they must expect the bitter waters of affliction, but, if otherwise, pleasant and good things: or, "there he proved him" (q); Moses, his obedience and faith, by ordering him to cast in the tree he showed him; but the former sense seems best to agree with what follows.

When Moses cried to the Lord in consequence, He showed him some wood which, when thrown into the water, took away its bitterness. The Bedouins, who know the neighbourhood, are not acquainted with such a tree, or with any other means of making bitter water sweet; and this power was hardly inherent in the tree itself, though it is ascribed to it in Ecclus. 38:5, but was imparted to it through the word and power of God. We cannot assign any reason for the choice of this particular earthly means, as the Scripture says nothing about any "evident and intentional contrast to the change in the Nile by which the sweet and pleasant water was rendered unfit for use" (Kurtz). The word עץ "wood" (see only Numbers 19:6), alone, without anything in the context to explain it, does not point to a "living tree" in contrast to the "dead stick." And if any contrast had been intended to be shown between the punishment of the Egyptians and the training of the Israelites, this intention would certainly have been more visibly and surely accomplished by using the staff with which Moses not only brought the plagues upon Egypt, but afterwards brought water out of the rock. If by עץ we understand a tree, with which ויּשׁלך, however, hardly agrees, it would be much more natural to suppose that there was an allusion to the tree of life, especially if we compare Genesis 2:9 and Genesis 3:22 with Revelation 22:2, "the leaves of the tree of life were for the healing of the nations," though we cannot regard this reference as established. All that is clear and undoubted is, that by employing these means, Jehovah made Himself known to the people of Israel as their Physician, and for this purpose appointed the wood for the healing of the bitter water, which threatened Israel with disease and death (2 Kings 4:40).

By this event Jehovah accomplished two things: (a) "there He put (made) for it (the nation) an ordinance and a right," and (b) "there He proved it." The ordinance and right which Jehovah made for Israel did not consist in the words of God quoted in Exodus 15:26, for they merely give an explanation of the law and right, but in the divine act itself. The leading of Israel to bitter water, which their nature could not drink, and then the sweetening or curing of this water, were to be a חק for Israel, i.e., an institution or law by which God would always guide and govern His people, and a משׁפּט or right, inasmuch as Israel could always reckon upon the help of God, and deliverance from every trouble. But as Israel had not yet true confidence in the Lord, this was also a trial, serving to manifest its natural heart, and, through the relief of its distress on the part of God, to refine and strengthen its faith. The practical proof which was given of Jehovah's presence was intended to impress this truth upon the Israelites, that Jehovah as their Physician would save them from all the diseases which He had sent upon Egypt, if they would hear His voice, do what was right in His eyes, and keep all His commandments.

And he cried unto the LORD; and the LORD shewed him a tree, which when he had cast into the waters, the waters were made sweet: there he made for them a statute and an ordinance, and there {n} he proved them,

(n) That is, God, or Moses in God's name.

15:25 And he cried unto the Lord - It is the greatest relief of the cares of magistrates and ministers, when those under their charge make them uneasy, that they may have recourse to God by prayer; he is the guide of the church's guides, and to the chief shepherd, the under shepherds must on all occasions apply themselves: And the Lord directed Moses to a tree, which he cast into the waters, and they were made sweet - Some think this wood had a peculiar virtue in it for this purpose, because it is said, God shewed him the tree. God is to be acknowledged, not only in the creating things useful for man, but in discovering their usefulness. But perhaps this was only a sign, and not a means of the cure, no more than the brazen serpent. There he made a statute and an ordinance, and there he proved them - That is, there he put them upon trial, admitted them as probationers for his favour. In short he tells them, Exo 15:26, what he expected from them, and that was, in one word, obedience. They must diligently hearken to his voice, and give ear to his commandments, and must take care, in every thing, to do that which was right in God's sight, and to keep all his statutes. Then I will put none of these diseases upon thee - That is, I will not bring upon thee any of the plagues of Egypt. This intimates, that if they were disobedient, the plagues which they had seen inflicted on their enemies should be brought on them. But if thou wilt be obedient, thou shalt be safe, the threatening is implied, but the promise is expressed, I am the Lord that healeth thee - And will take care of thee wherever thou goest.

[1] when he had cast into the waters

These bitter waters were in the very path of the Lord's leading, and stand for the trials of God's people, which are educatory and not punitive. The "tree" is the cross Gal 3:13 which became sweet to Christ as the expression of the Father's will Jn 18:11. When our Marahs are Song taken we cast the "tree" into the waters. Rom 5:3,4.

25. the Lord showed him a tree, which when he had cast into the waters, the waters were made sweet-Some travellers have pronounced this to be the Elvah of the Arabs-a shrub in form and flower resembling our hawthorn; others, the berries of the Ghurkhud-a bush found growing around all brackish fountains. But neither of these shrubs are known by the natives to possess such natural virtues. It is far more likely that God miraculously endowed some tree with the property of purifying the bitter water-a tree employed as the medium, but the sweetening was not dependent upon the nature or quality of the tree, but the power of God (compare Joh 9:6). And hence the "statute and ordinance" that followed, which would have been singularly inopportune if no miracle had been wrought.

and there he proved them-God now brought the Israelites into circumstances which would put their faith and obedience to the test (compare Ge 22:1).

15:22-27 In the wilderness of Shur the Israelites had no water. At Marah they had water, but it was bitter; so that they could not drink it. God can make bitter to us that from which we promise ourselves most, and often does so in the wilderness of this world, that our wants, and disappointments in the creature, may drive us to the Creator, in whose favour alone true comfort is to be had. In this distress the people fretted, and quarrelled with Moses. Hypocrites may show high affections, and appear earnest in religious exercises, but in the time of temptation they fall away. Even true believers, in seasons of sharp trial, will be tempted to fret, distrust, and murmur. But in every trial we should cast our care upon the Lord, and pour out our hearts before him. We shall then find that a submissive will, a peaceful conscience, and the comforts of the Holy Ghost, will render the bitterest trial tolerable, yea, pleasant. Moses did what the people had neglected to do; he cried unto the Lord. And God provided graciously for them. He directed Moses to a tree which he cast into the waters, when, at once, they were made sweet. Some make this tree typical of the cross of Christ, which sweetens the bitter waters of affliction to all the faithful, and enables them to rejoice in tribulation. But a rebellious Israelite shall fare no better than a rebellious Egyptian. The threatening is implied only, the promise is expressed. God is the great Physician. If we are kept well, it is he that keeps us; if we are made well, it is he that recovers us. He is our life and the length of our days. Let us not forget that we are kept from destruction, and delivered from our enemies, to be the Lord's servants. At Elim they had good water, and enough of it. Though God may, for a time, order his people to encamp by the bitter waters of Marah, that shall not always be their lot. Let us not faint at tribulations.
