Deuteronomy 6:21-23

then you shall say to your son, ‘We were Pharaoh’s slaves in Egypt. And the LORD brought us out of Egypt with a mighty hand. And the LORD showed signs and wonders, great and grievous, against Egypt and against Pharaoh and all his household, before our eyes. And he brought us out from there, that he might bring us in and give us the land that he swore to give to our fathers.
