The pagan are guilty of but one sin - idolatry; the covenant-people commit two - they abandon the true God; they serve idols.

Fountain - Not a spring or natural fountain, but a tank or reservoir dug in the ground (see Jeremiah 6:7), and chiefly intended for storing living waters, i. e., those of springs and rivulets. The cistern was used for storing up rain-water only, and therefore the quantity it contained was limited.

Two evils - First, they forsook God, the Fountain of life, light, prosperity, and happiness. Secondly, they hewed out broken cisterns; they joined themselves to idols, from whom they could receive neither temporal nor spiritual good! Their conduct was the excess of folly and blindness. What we call here broken cisterns, means more properly such vessels as were ill made, not staunch, ill put together, so that the water leaked through them.

For my people have committed two evils,.... Not but that they had committed more, but there were two principal ones they were guilty of, hereafter mentioned; and it was an aggravation of these crimes, that they were the professing people of God who had committed them: and it may be observed, that such sin; they are not without it, nor the commission of it; and may be left to fall into great sins, and yet remain his people; covenant interest cannot be dissolved; this should be considered not as an encouragement to sin, but as a relief under a sense of sin:

they have forsaken me, the fountain of living waters; this is said of Christ, Sol 4:15, grace in him is compared to "water", it being cooling and refreshing, cleansing and fructifying; and to living water, because it quickens dead sinners, revives drooping saints, supports and maintains spiritual life, and issues in eternal life; and because it is perpetual and ever flowing; and to a "fountain", denoting that the original of it is in Christ, and the great abundance of it which is in him; it is as water in a fountain, in us as in streams: now to forsake this fountain is the first of these evils; which is done when the people of God are remiss in the exercise of faith on Christ; grow cold in their affections to him, and neglect his word and ordinances.

And hewed them out cisterns, broken cisterns, that can hold no water; this is the other evil; and such are the world, and the things in it, when cleaved unto, and rest and satisfaction are taken in them; the inventions and ordinances of men, when followed and attended to; moral duties, and evangelical services, when depended on; and even spiritual frames, when these are lived upon, and put in the room of Christ; yea, acts of faith, when they are rested in, and the object not so much regarded as should be: moreover, what may principally be intended are, in the first place, forsaking the worship of God, as the Targum interprets it, the assembling of themselves together to attend his service and ordinances, which is to forsake their own mercies; and, in the next place, following after idols, as the same paraphrase explains it, which have no divinity in them, and can yield no help and relief, or give any comfort, or afford any supply in time of distress and need. It is egregious folly to leave a fountain for a cistern, and especially a broken one: in a fountain the water is living, and always running, and ever springing up; not so in a cistern, and in a broken cistern there is none at all.

For my people have committed two evils; they have forsaken me {t} the fountain of living waters, and hewed out for themselves cisterns, broken cisterns, that can hold no water.

(t) Signifying that when men forsake God's word, which is the fountain of life, they reject God himself, and so fall to their own inventions, and vain confidence, and procure to themselves destruction, Jon 2:8, Zec 10:2.

2:13 Of living waters - A metaphor taken from springs, called living, because they never cease, or intermit; such had God's care and kindness been over them. Cisterns - Either their idols, which are empty vain things, that never answer expectation, or the Assyrians, and Egyptians. Indeed all other supports, that are trusted to besides God, are but broken vessels.

13. two evils-not merely one evil, like the idolaters who know no better; besides simple idolatry, My people add the sin of forsaking the true God whom they have known; the heathen, though having the sin of idolatry, are free from the further sin of changing the true God for idols (Jer 2:11).

forsaken me-The Hebrew collocation brings out the only living God into more prominent contrast with idol nonentities. "Me they have forsaken, the Fountain," &c. (Jer 17:13; Ps 36:9; Joh 4:14).

broken cisterns-tanks for rain water, common in the East, where wells are scarce. The tanks not only cannot give forth an ever-flowing fresh supply as fountains can, but cannot even retain the water poured into them; the stonework within being broken, the earth drinks up the collected water. So, in general, all earthly, compared with heavenly, means of satisfying man's highest wants (Isa 55:1, 2; compare Lu 12:33).

2:9-13 Before God punishes sinners, he pleads with them, to bring them to repentance. He pleads with us, what we should plead with ourselves. Be afraid to think of the wrath and curse which will be the portion of those who throw themselves out of God's grace and favour. Grace in Christ is compared to water from a fountain, it being cooling and refreshing, cleansing and making fruitful: to living water, because it quickens dead sinners, revives drooping saints, supports and maintains spiritual life, and issues in eternal life, and is ever-flowing. To forsake this Fountain is the first evil; this is done when the people of God neglect his word and ordinances. They hewed them out broken cisterns, that could hold no water. Such are the world, and the things in it; such are the inventions of men when followed and depended on. Let us, with purpose of heart, cleave to the Lord only; whither else shall we go? How prone are we to forego the consolations of the Holy Spirit, for the worthless joys of the enthusiast and hypocrite!
