Thou shalt not adore them, nor serve them: I am the Lord thy God, mighty, jealous, visiting the iniquity of the fathers upon the children, unto the third and fourth generation of them that hate me:

Thou dost not bow thyself to them, nor serve them: for I, Jehovah thy God, am a zealous God, charging iniquity of fathers on sons, on the third generation, and on the fourth, of those hating Me,

You may not go down on your faces before them or give them worship: for I, the Lord your God, am a God who will not give his honour to another; and I will send punishment on the children for the wrongdoing of their fathers, to the third and fourth generation of my haters;

you must not bow yourself down to them, nor serve them, for I, the LORD your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and on the fourth [generation] of those who hate me,

You shall not adore them, nor shall you worship them. I am the Lord your God: strong, zealous, visiting the iniquity of the fathers on the sons to the third and fourth generation of those who hate me,

Non adorabis ea, neque coles ea, ego enim Jehova Deus tuus, Deus zelotes, visitans iniquitatem patrum super filios, in tertiam et quartam generationem in his qui me oderunt:

Jealous God - This shows in a most expressive manner the love of God to this people. He felt for them as the most affectionate husband could do for his spouse; and was jealous for their fidelity, because he willed their invariable happiness.
Visiting the iniquity of the fathers upon the children - This necessarily implies - if the children walk in the steps of their fathers; for no man can be condemned by Divine justice for a crime of which he was never guilty; see Ezekiel 18. Idolatry is however particularly intended, and visiting sins of this kind refers principally to national judgments. By withdrawing the Divine protection the idolatrous Israelites were delivered up into the hands of their enemies, from whom the gods in whom they had trusted could not deliver them. This God did to the third and fourth generations, i.e., successively; as may be seen in every part of the Jewish history, and particularly in the book of Judges. And this, at last, became the grand and the only effectual and lasting means in his hand of their final deliverance from idolatry; for it is well known that after the Babylonish captivity the Israelites were so completely saved from idolatry, as never more to have disgraced themselves by it as they had formerly done. These national judgments, thus continued from generation to generation, appear to be what are designed by the words in the text, Visiting the sins of the fathers upon the children, etc.

Thou shalt not (c) bow down thyself to them, nor serve them: for I the LORD thy God [am] a (d) jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth [generation] of them that hate me;
(c) By this outward gesture, all forms of service and worship to idols is forbidden.
(d) And will have revenge on those who condemn my honour.

Thou shall not bow down thyself to them,.... Perform any worship to them, show any reverence of them by any gesture of the body; one being mentioned, bowing the body, and put for all others, as prostration of it to the earth, bending the knee, kissing the hand, lifting up of hands or eyes to them, or by any outward action expressing a religious esteem of them, as if there was divinity in them:
nor serve them; in a religious manner, internally or externally, by offering sacrifice and burning incense to them; by praying to, or praising of them; by expressing love to them, faith and trust in them, hope and expectation of good things from them, and the like. The reason of this second command, relating to the making and worshipping of images, next follows:
for I the Lord thy God am a jealous God; jealous of his own honour and glory, and will not give it to another; even to graven images, nor suffer it to be given to them without resenting it; and jealousy is fierce and cruel, and breaks forth into great wrath, and issues in dreadful scenes oftentimes among men; as a man that has reason to be jealous of his wife, and especially if he takes her and the adulterer in the fact, it often costs them both their lives, being so enraged at such an insult upon him, and such a violation of the marriage bed; and thus the great Jehovah, the God of Israel, their head and husband, is represented, in order to deter from idolatry, or spiritual adultery, than which nothing could be more provoking to him:
visiting the iniquity of the fathers upon the children; meaning chiefly, if not solely, the iniquity of idolatry; which being such an insult on his honour, "crimen laesae majestatis", is treated by him as high treason is among men; not only he punishes the authors and perpetrators of it in their own persons, which is meant by "visiting", but upon their children also, which are parts of themselves; and whatsoever is inflicted on them is the same as on themselves, and is an addition to, and a sensible aggravation of their punishment; and especially these are visited in such a manner, when they tread in their father's steps, and fill up the measure of their iniquity. So the Targum of Jonathan,"visiting the iniquity of ungodly fathers on rebellious children:
unto the third and fourth generation of them that hate me; as all idolaters must be thought to do, whatsoever love and affection they may pretend to God, by worshipping idols before him, besides him, along with him, or him in them: "the third and fourth generation" are mentioned, because sometimes parents lived to see these, and so with their eyes beheld the punishment inflicted upon their posterity for their sins, which must be distressing to them; or, however, these being but small removes from them, might impress their minds and affect them, to think what their sins would bring upon their descendants, who would quickly come after them, and share in the sad effects of their iniquities, and so be a means to deter them from them.
