20. And so shall you do on the seventh day of the month, on behalf of each one who was ignorant or who was deceived by error. And you shall make expiation for the house.
21. In the first month, the fourteenth day of the month shall be for you the solemnity of the Passover. For seven days, unleavened bread shall be eaten.
