Exodus 6:5-9

Moreover, I have heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered my covenant. “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. 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. 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.’ ” Moses reported this to the Israelites, but they did not listen to him because of their discouragement and harsh labor.
