and tell them that this is what the Lord GOD says: On the day I chose Israel, I swore an oath to the descendants of the house of Jacob and made Myself known to them in the land of Egypt. With an uplifted hand I said to them, ‘I am the LORD your God.’
The LORD recalls choosing Israel and revealing Himself to Jacob's descendants in Egypt with an oath.
This verse begins the covenant history at its electing origin.
1In the seventh year, on the tenth day of the fifth month, some of the elders of Israel came to inquire of the LORD, and they sat down before me. 2Then the word of the LORD came to me, saying, 3“Son of man, speak to the elders of Israel and tell them that this is what the Lord GOD says: Have you come to inquire of Me? As surely as I live, I will not be consulted by you, declares the Lord GOD. 4Will you judge them, will you judge them, son of man? Confront them with the abominations of their fathers 5and tell them that this is what the Lord GOD says: On the day I chose Israel, I swore an oath to the descendants of the house of Jacob and made Myself known to them in the land of Egypt. With an uplifted hand I said to them, ‘I am the LORD your God.’ 6On that day I swore to bring them out of the land of Egypt into a land that I had searched out for them, a land flowing with milk and honey, the glory of all lands. 7And I said to them: ‘Each of you must throw away the abominations before his eyes, and you must not defile yourselves with the idols of Egypt. I am the LORD your God.’ 8But they rebelled against Me and refused to listen. None of them cast away the abominations before their eyes, and they did not forsake the idols of Egypt. So I resolved to pour out My wrath upon them and vent My anger against them in the land of Egypt. 9But I acted for the sake of My name, that it should not be profaned in the eyes of the nations among whom they were living, in whose sight I had revealed Myself to Israel by bringing them out of the land of Egypt.
