Leviticus 18:2

“Speak unto the children of Israel, etc.] 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…”

“18:2 Many Near Eastern treaties began with the name and titles of the ruler who was drawing up the treaty. The phrase I am the Lord your God gives the name of the Great King, Yahweh (English the Lord), followed by his title, your God (see also Exod 20:2; Deut 5:6). These words were an abbreviated way to invoke Israel’s covenant with God and all that it implied. By reminding the people that they were the Lord’s, these words carried an authority that required a response (Lev 11:44; 18:4-5). Chapter 18 begins and ends (18:30) with these words, and they appear frequently throughout chs 19–26.”
