Exodus 13:10

⁸And thou shalt tell thy son in that day, saying, Therefore the Lord dealt thus with me, as I was going out of Egypt.

⁹And it shall be to thee a sign upon thy hand and a memorial before thine eyes, that the law of the Lord may be in thy mouth, for with a strong hand the Lord God brought thee out of Egypt.

— Exodus 13:10 —

¹¹And it shall come to pass when the Lord thy God shall bring thee into the land of the Canaanites, as he swore to thy fathers, and shall give it thee,

¹²that thou shalt set apart every offspring opening the womb, the males to the Lord, every one that opens the womb out of the herds or among thy cattle, as many as thou shalt have: thou shalt sanctify the males to the Lord.
