Exodus 13:8
And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt. And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt.
Exodus 13:8 belongs to the history of Israel's deliverance from Egypt. That deliverance was God's mighty work in saving Israel. Its saving power was seen especially in the miraculous crossing of the Red Sea.
