Deuteronomy 6:22-25

Moreover, the LORD showed great and distressing signs and wonders before our eyes against Egypt, Pharaoh and all his household; He brought us out from there in order to bring us in, to give us the land which He had sworn to our fathers.’ So the LORD commanded us to observe all these statutes, to fear the LORD our God for our good always and for our survival, as it is today. It will be righteousness for us if we are careful to observe all this commandment before the LORD our God, just as He commanded us.
