Exodus 6:5-6
6:5 I have also heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered my covenant.
6:6 Therefore, tell the Israelites, ‘I am the Lord. I will bring you out from your enslavement to the Egyptians, I will rescue you from the hard labor they impose, and I will redeem you with an outstretched arm and with great judgments.
