Exodus 6:5-8
5 Moreover, I have heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered my covenant.
6 “Therefore, say to the Israelites: ‘I am the Lord, and I will bring you out from under the yoke of the Egyptians. I will free you from being slaves to them, and I will redeem you with an outstretched arm and with mighty acts of judgment. 7 I will take you as my own people, and I will be your God. Then you will know that I am the Lord your God, who brought you out from under the yoke of the Egyptians. 8 And I will bring you to the land I swore with uplifted hand to give to Abraham, to Isaac and to Jacob. I will give it to you as a possession. I am the Lord.’”
