John 4:22 - Joseph Benson’s Commentary on the Old and New Testaments

Ye worship ye know not what Or rather, as the original words, υμεις προσκυνειτε ο ουκ οιδατε, ye worship what ye know not, that is, ye Samaritans are ignorant, not only of the place, but, in a great measure, also of the very object of worship. They believed indeed, in a sense, in the one living and true God, as the Jews did; drawing their knowledge of him from the five books of Moses, the authority of which they acknowledged. But as they did not receive the writings of the prophets as canonical, or of divine inspiration, it is not to be supposed that they were, in general, so well acquainted with God, and the service he required, as the Jews were. On the contrary, it is probable that they were sunk into a state of gross ignorance in these respects. For, if the writings of the prophets were of importance for conveying to mankind the knowledge of the perfections and will of God, the Samaritans, who rejected all those writings, must, on this head, have been more ignorant than the Jews. Doubtless, many of them were like their progenitors, of whom we read, (2 Kings 17:32,) that they feared the Lord, namely, after a fashion; but, at the same time, served their own gods, that is, they joined the worship of idols with his worship: or worshipped him merely as a local deity, as is plainly intimated, Joh 4:26-27 of that chapter, where they twice term him, the God of the land. We know what we worship Or rather, as the Greek is, we worship what we know, or, we know the God we worship. Our Lord and his disciples, and such Jews as were pious, certainly knew the God they worshipped; and the Jews in general had much more correct ideas of the nature and attributes of God than the Samaritans had. Christ elsewhere condemns the corruptions of the Jewish worship; yet here defends their worship with regard to its object: for we may be right with respect to the object of our worship, even when there is much that is faulty and corrupt in the manner of it. For salvation is of the Jews All the prophets spoke of the Saviour as one that should come out of the Jewish nation, and that through him the knowledge of the true God, and of the true way of worshipping and serving him, should be communicated to the rest of mankind. For, as the author of salvation came of the Jews, appeared among them, and was sent first to bless them, affording them, in an extraordinary way, the means of salvation; so the word of salvation was of them, and was delivered to them, to be derived from them to other nations. This was a sure guide to them in their worship, and they who followed it knew what they worshipped. As they, therefore, were thus privileged and advanced, it was presumption for the Samaritans to vie with them.
