Exodus 13:6-8

Darby Translation

⁶ Seven days shalt thou eat unleavened bread; and in the seventh day is a feast to Jehovah.

⁷ Unleavened bread shall be eaten the seven days; and leavened bread shall not be seen with thee, neither shall there be leaven seen with thee in all thy borders.

⁸ And thou shalt inform thy son in that day, saying, It is because of what Jehovah did to me when I came out of Egypt.
