யாத்திராகமம் 13:6-8
6
Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD.
7
Unleavened bread shall be eaten seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters.
8
And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt.
