John 4:22

Ye worship ye know not what - The Samaritans believed in the same God with the Jews; but, as they rejected all the prophetical writings, they had but an imperfect knowledge of the Deity: besides, as they incorporated the worship of idols with his worship, they might be justly said to worship him whom they did not properly know. See the account of their motley worship, 2 Kings 17:26-34. But after Sanballat had built the temple on Mount Gerizim, the idolatrous worship of the Cutheans and Sepharvites, etc., was entirely laid aside; the same religious service being performed in the Samaritan temple which was performed in that at Jerusalem.

We know what we worship - We Jews acknowledge all the attributes of his nature, and offer to him only the sacrifices prescribed in the law.

Salvation is of the Jews - Εκ των Ιουδαιων εστιν, Salvation is from the Jews. Salvation seems here to mean the Savior, the Messiah, as it does Luke 2:30; Acts 4:12 : and so the woman appears to have understood it, John 4:25. The Messiah was to spring from the Jews - from them, the preaching of the Gospel, and the knowledge of the truth, were to go to all the nations of the world. It was to the Jews that the promises were made; and it was in their prophetic Scriptures, which the Samaritans rejected, that Jesus Christ was proclaimed and described. See Isaiah 11:3.

Ye worship ye know not what - This probably refers to the comparative ignorance and corruption of the Samaritan worship. Though they received the five books of Moses, yet they rejected the prophets, and of course all that the prophets had said respecting the true God. Originally, also, they had joined the worship of idols to that of the true God. See 2 Kings 17:26-34. They had, moreover, no authority for building their temple and conducting public worship by sacrifices there. On all these accounts they were acting in an unauthorized manner. They were not obeying the true God, nor offering the worship which he had commanded or would approve. Thus, Jesus indirectly settled the question which she had proposed to him, yet in such a way as to show her that it was of much less importance than she had supposed.

We know - We Jews. This they knew because God had commanded it; because they worshipped in a place appointed by God, and because they did it in accordance with the direction and teaching of the prophets.

Salvation is of the Jews - They have the true religion and the true form of worship; and the Messiah, who will bring salvation, is to proceed from them. See Luke 2:30; Luke 3:6. Jesus thus affirms that the Jews had the true form of the worship of God. At the same time he was sensible how much they had corrupted it, and on various occasions reproved them for it.

4:22 Ye worship ye know not what - Ye Samaritans are ignorant, not only of the place, but of the very object of worship. Indeed, they feared the Lord after a fashion; but at the same time served their own gods, 17:33 .Salvation is from the Jews - So spake all the prophets, that the Saviour should arise out of the Jewish nation: and that from thence the knowledge of him should spread to all nations under heaven.
