John Gill Bible Commentary

Speak unto the children of Israel,.... To the heads of their tribes, that they might deliver to them the following laws; or Moses is bid to publish them among them, either by word of mouth, or by writing, or both: and say unto them, I am the Lord your God; with which they were to be introduced; showing the right he had to enact and enjoin such laws, since he was Jehovah, the Being of beings, and from whom they received their beings; their sovereign Lord and King, who had a right to rule over them, and command what he pleased; and also the obligation they lay under to him to regard them, and yield a cheerful obedience to them, since he was their God, not only that had made them, but had redeemed them out of Egypt; and who had made a covenant with them, and had taken special care of them, and had bestowed many wonderful favours on them; and for this purpose is this phrase often used in this chapter, and very frequently in the next. See Lev 18:2.
