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. — Exodus 6:7
In the book of Exodus we have the record of the splitting of the Red Sea. In this splitting of the Red Sea, God’s people, in a covenant ceremony, pass through the beast that was cut in twain by God and so re-established Covenant with God. That God took the Red Sea covenant ceremony seriously, and took up the role of the Protector King over a vassal people, is seen in the fact that He saved His people through a judgment that spilled the life blood of Egypt.
The Red Sea was split. God’s covenant people passed through the parts. The blood that sealed the covenant was the Egyptians. God’s people, who all passed through the sea, were Baptized (sprinkled) into Moses who was a type of Christ.
In the Red Sea covenant ceremony God re-confirmed what He had said to Abraham long ago… “You shall be my people and I will be your God.”
