The gift of God - The word "gift," here denotes "favor." It may refer to Jesus Himself, as the gift of God to the world, given to save men from death John 3:16; 2 Corinthians 9:15, or it may refer to the opportunity then afforded her of seeking salvation. If thou knewest how favorable an opportunity God now gives thee to gain a knowledge of himself, etc.

And who it is ... - If thou knewest that the Messiah was speaking.

Living water - The Jews used the expression "living water" to denote springs, fountains, or running streams, in opposition to dead and stagnant water. Jesus here means to denote by it his doctrine, or his grace and religion, in opposition to the impure and dead notions of the Jews and the Samaritans. See John 4:14. This was one of the many instances in which he took occasion from common topics of conversation to introduce religious discourse. None ever did it so happily as he did, but, by studying his example and manner, we may learn also to do it. One way to acquire the art is to have the mind full of the subject; to make religion our first and main thing; to carry it with us into all employments and into all society; to look upon everything in a religious light, and out of the abundance of the heart the mouth will speak, Matthew 12:34.

If thou knewest the gift of God - Δωρεαν signifies a free gift. A gift is any thing that is given, for which no equivalent has been or is to be returned: a free gift is that which has been given without asking or entreaty. Such a gift of kindness was Jesus Christ to the world, John 3:16; and through him comes the gift of the Spirit, which those who believe on his name were to receive. Christ was not an object of desire to the world - no man asked for him; and God, moved thereto by his own eternal mercy, freely gave him. Through this great gift comes the Holy Spirit, and all other gifts which are necessary to the salvation of a lost world.

Living water - By this expression, which was common to the inhabitants both of the east and of the west, is always meant spring water, in opposition to dead, stagnant water contained in ponds, pools, tanks, or cisterns; and what our Lord means by it is evidently the Holy Spirit, as may be seen, John 7:38, John 7:39.

As water quenches the thirst, refreshes and invigorates the body, purifies things defiled, and renders the earth fruitful, so it is an apt emblem of the gift of the Holy Ghost, which so satisfies the souls that receive it that they thirst no more for earthly good: it purifies also from all spiritual defilement, on which account it is emphatically styled the Holy Spirit; and it makes those who receive it fruitful in every good word and work.

Jesus answered and said unto her,.... In a very serious manner, in a different way from hers:

if thou knewest the gift of God; meaning, not the Holy Spirit with his gifts and graces, as some think, but himself; for the following clause is explanatory of it;

and who it is that saith to thee, give me to drink; and Christ is also spoken of in the Old Testament, as the gift of God, Isaiah 9:6 and he had lately spoken of himself as such, John 3:16 and he is, by way of eminency, "the gift of God"; which is comprehensive of all others, is exceeding large, and very suitable to the wants and cases of men; and is irrevocable, unchangeable, and unspeakable: for he is God's gift, as he is his own and only begotten Son; and he is given for a covenant to the people, with all the promises and blessings of it; and as an head, both of eminence and influence; and to be a Saviour of them, and a sacrifice for their sins; and as the bread of life, for them to feed and live upon; of which gift, men are naturally ignorant, as this woman was: they know not the dignity of his person; nor the nature and usefulness of his offices; nor the way of peace, righteousness, and salvation by him; nor do they see any amiableness, or loveliness in him; and whatever notional knowledge some natural men may have of him, they know him not spiritually and experimentally, or as the gift of God to them:

thou wouldst have asked of him; a favour and benefit; for such who truly know Christ, the worth and value of him, and their need of him, will apply to him for grace, as they have encouragement to do; since all grace is treasured up in him, and he gives it freely, and upbraideth not; and souls are invited to ask it of him, and take it freely; nor is it to be had anywhere else: but knowledge of Christ, is absolutely necessary, to asking anything of him; for till he is known, he will not be applied to; but when he is made known to any, in his fulness and suitableness, they will have recourse to him, and ask grace and mercy of him; and which is freely had: the Vulgate Latin very wrongly adds, "perhaps"; reading it, "perhaps thou wouldst have asked"; whereas our Lord's meaning is, that she would certainly have asked:

and he would have given thee living water; pardoning and justifying grace, every branch of sanctifying grace, and all the supplies of it; so called, because his grace quickens sinners dead in sin, and dead in law, and in, their own apprehensions; and causes them to live in themselves, and before God; and because it refreshes and comforts, revives and cheers, and is like rivers of water in a dry land; and because it maintains and supports spiritual life in their souls; and it ever abides, and continues, and springs up unto everlasting life: for the allusion is to spring water, that bubbles up in a fountain, and is ever running; for such water the Jews call "living water"; see Genesis 26:19; where in the Hebrew text it is "living water"; which we, and also the Chaldee paraphrase, render "springing water". So living waters with them, are said to be always flowing, and never cease (t).

(t) Bartenora in Misn. Negaim, c. 14. sect. 1.

If thou knewest, etc.

Answering rather something latent in the question than the question itself, as in Jesus' first answer to Nicodemus.

The gift (δωρεὰν)

Only here in the Gospels, though Luke uses it in Acts four times, and the kindred adverb, δῶρημα, freely, is found once in Matthew. The word carries the sense of a bountiful, free, honorable gift. Compare δῶρημα, gift, and see on James 1:17.

Asked (ᾔτησας)

Jesus uses the same word for ask which the woman had employed of his asking her, the word expressing the asking of the inferior from the superior. Here it is the appropriate word.

Living water (ὕδωρ ζῶν)

Fresh, perennial. A familiar figure to the Jews. See Jeremiah 2:13; Jeremiah 17:13; Zechariah 14:8. Not necessarily the same as water of life (ὕδωρ ζωῆς, Revelation 21:6; Revelation 22:1, Revelation 22:17).

Jesus answered and said unto her, If thou knewest {d} the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee {e} living water.

(d) By this word the we are shown that Christ speaks of some excellent gift, that is to say, even about himself, whom his Father offered to this woman.

(e) This everlasting water, that is to say, the exceeding love of God, is called living or of life, to make a difference between it and the water that should be drawn out of a well: and these metaphors are frequently used by the Jews.

4:10 If thou knewest the gift of God, etc. The great gift of God is not water, not even peace of soul, but Christ himself, God's unspeakable gift (2Co 9:15), God gave his only begotten Son (Joh 3:16). Had she known, the Savior declares, Thou wouldest have asked of him, and he would have given thee living water. Observe: (1) That Christ asks a favor in order to confer a greater one. (2) The well and the water suggest the thirst of the soul and the waters of life.

Living water. Water of life. The woman thought he meant running water.

4:10 If thou hadst known the gift - The living water; and who it is - He who alone is able to give it: thou wouldst have asked of him - On those words the stress lies. Water - In like manner he draws the allegory from bread, John 6:27, and from light, 8:12; the first, the most simple, necessary, common, and salutary things in nature. Living water - The Spirit and its fruits. But she might the more easily mistake his meaning, because living water was a common phrase among the Jews for spring water.

10. If thou knewest, &c.-that is, "In Me thou seest only a petitioner to thee but if thou knewest who that Petitioner is, and the Gift that God is giving to men, thou wouldst have changed places with Him, gladly suing of Him living water-nor shouldst thou have sued in vain" (gently reflecting on her for not immediately meeting His request).

4:4-26 There was great hatred between the Samaritans and the Jews. Christ's road from Judea to Galilee lay through Samaria. We should not go into places of temptation but when we needs must; and then must not dwell in them, but hasten through them. We have here our Lord Jesus under the common fatigue of travellers. Thus we see that he was truly a man. Toil came in with sin; therefore Christ, having made himself a curse for us, submitted to it. Also, he was a poor man, and went all his journeys on foot. Being wearied, he sat thus on the well; he had no couch to rest upon. He sat thus, as people wearied with travelling sit. Surely, we ought readily to submit to be like the Son of God in such things as these. Christ asked a woman for water. She was surprised because he did not show the anger of his own nation against the Samaritans. Moderate men of all sides are men wondered at. Christ took the occasion to teach her Divine things: he converted this woman, by showing her ignorance and sinfulness, and her need of a Saviour. By this living water is meant the Spirit. Under this comparison the blessing of the Messiah had been promised in the Old Testament. The graces of the Spirit, and his comforts, satisfy the thirsting soul, that knows its own nature and necessity. What Jesus spake figuratively, she took literally. Christ shows that the water of Jacob's well yielded a very short satisfaction. Of whatever waters of comfort we drink, we shall thirst again. But whoever partakes of the Spirit of grace, and the comforts of the gospel, shall never want that which will abundantly satisfy his soul. Carnal hearts look no higher than carnal ends. Give it me, saith she, not that I may have everlasting life, which Christ proposed, but that I come not hither to draw. The carnal mind is very ingenious in shifting off convictions, and keeping them from fastening. But how closely our Lord Jesus brings home the conviction to her conscience! He severely reproved her present state of life. The woman acknowledged Christ to be a prophet. The power of his word in searching the heart, and convincing the conscience of secret things, is a proof of Divine authority. It should cool our contests, to think that the things we are striving about are passing away. The object of worship will continue still the same, God, as a Father; but an end shall be put to all differences about the place of worship. Reason teaches us to consult decency and convenience in the places of our worship; but religion gives no preference to one place above another, in respect of holiness and approval with God. The Jews were certainly in the right. Those who by the Scriptures have obtained some knowledge of God, know whom they worship. The word of salvation was of the Jews. It came to other nations through them. Christ justly preferred the Jewish worship before the Samaritan, yet here he speaks of the former as soon to be done away. God was about to be revealed as the Father of all believers in every nation. The spirit or the soul of man, as influenced by the Holy Spirit, must worship God, and have communion with him. Spiritual affections, as shown in fervent prayers, supplications, and thanksgivings, form the worship of an upright heart, in which God delights and is glorified. The woman was disposed to leave the matter undecided, till the coming of the Messiah. But Christ told her, I that speak to thee, am He. She was an alien and a hostile Samaritan, merely speaking to her was thought to disgrace our Lord Jesus. Yet to this woman did our Lord reveal himself more fully than as yet he had done to any of his disciples. No past sins can bar our acceptance with him, if we humble ourselves before him, believing in him as the Christ, the Saviour of the world.
