Exodus 13:3; Exodus 13:9

3 Moses said to the people, "Remember this day in which you went out from Egypt, from the house of slavery; for by a powerful hand the LORD brought you out from this place. And nothing leavened shall be eaten.

9 "And it shall serve as a sign to you on your hand, and as a reminder on your forehead , that the law of the LORD may be in your mouth; for with a powerful hand the LORD brought you out of Egypt.
