והגדת לבנך

And it shall be when the LORD shall bring thee into the land of the Canaanite, and the Hittite, and the Amorite, and the Hivite, and the Jebusite, which He swore unto thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month. Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD. Unleavened bread shall be eaten throughout the seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee, in all thy borders. And thou shalt tell thy son in that day, saying: It is because of that which the LORD did for me when I came forth out of Egypt.
