20:5 And say to them, Thus saith the Lord GOD; In the day when I chose Israel, and {c} lifted up my hand to the seed of the house of Jacob, and made myself known to them in the land of Egypt, when I lifted up my hand to them, saying, I [am] the LORD your God;
(c) I swore that I would be their God, which manner of oath was observed from all antiquity, where they used to lift up their hands toward the heavens, acknowledging God to be the author of truth and the defender of it, and also the judge of the heart, wishing that he would take vengeance, if they concealed anything which they knew to be truth.
20:5 When I chose - When I shewed that I had chosen them. The history of the rebellions of the children of Israel, begins as early, as their beginning. So does the history of man's apostasy from his Maker. No sooner have we read the story of his creation, but we meet with that of his rebellion. So we see here, it was with Israel; a people designed to represent the body of mankind, both in their dealings with God, and in God's dealing with them. Lifted up my hand - Or stretched out and made bare my arm; that is, magnified my power for their deliverance. When I lifted up mine hand - Shewed my power in performing my oath, and assuring them of doing what was farther promised.
20:1-9. Those hearts are wretchedly hardened which ask God leave to go on in sin, and that even when suffering for it; see ver.
