Exodus 6:6; Exodus 6:7

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.
