Deuteronomy 6:20 MSG

[20] The next time your child asks you, “What do these requirements and regulations and rules that God, our God, has commanded mean?” tell your child, “We were slaves to Pharaoh in Egypt and God powerfully intervened and got us out of that country. We stood there and watched as God delivered miracle-signs, great wonders, and evil-visitations on Egypt, on Pharaoh and his household. He pulled us out of there so he could bring us here and give us the land he so solemnly promised to our ancestors. That’s why God commanded us to follow all these rules, so that we would live reverently before God, our God, as he gives us this good life, keeping us alive for a long time to come.
