The Theocracy: or Immediate Government by God was Established On: The Right of Redemption

Therefore tell the Israelites: ‘I am the LORD, and I will bring you out from under the yoke of the Egyptians and deliver you from their bondage. 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 who is like Your people Israel—the one nation on earth whom God went out to redeem as a people for Himself and to make a name for Himself? You performed great and awesome wonders by driving out nations and their gods from before Your people, whom You redeemed for Yourself from Egypt.

For I am the LORD your God, the Holy One of Israel, your Savior; I give Egypt for your ransom, Cush and Seba in your place.
