Deuteronomy 6:20-25

20“When your son asks you in time to come, saying, ‘What is the meaning of the testimonies, the statutes, and the judgments which the Lord our God has commanded you?’

21then you shall say to your son: ‘We were slaves of Pharaoh in Egypt, and the Lord brought us out of Egypt with a mighty hand;

22and the Lord showed signs and wonders before our eyes, great and severe, against Egypt, Pharaoh, and all his household.

23Then He brought us out from there, that He might bring us in, to give us the land of which He swore to our fathers.

24And the Lord commanded us to observe all these statutes, to fear the Lord our God, for our good always, that He might preserve us alive, as it is this day.

25Then it will be righteousness for us, if we are careful to observe all these commandments before the Lord our God, as He has commanded us.’
