Exodus 6:5-7 New International Version - UK (NIVUK)
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.
