Deuteronomy 6:20-25

When thy son asketh thee in time to come, saying, What mean the testimonies, and the statutes, and the ordinances, which Jehovah our God hath commanded you? then thou shalt say unto thy son, We were Pharaoh’s bondmen in Egypt: and Jehovah brought us out of Egypt with a mighty hand; and Jehovah showed signs and wonders, great and sore, upon Egypt, upon Pharaoh, and upon all his house, before our eyes; and he brought us out from thence, that he might bring us in, to give us the land which he sware unto our fathers. And Jehovah commanded us to do all these statutes, to fear Jehovah our God, for our good always, that he might preserve us alive, as at this day. And it shall be righteousness unto us, if we observe to do all this commandment before Jehovah our God, as he hath commanded us.
