Exodus 13:6-8

DouayRheims(i) 6 Seven days shalt thou eat unleavened bread: and on the seventh day shall be the solemnity of the Lord. 7 Unleavened bread shall you eat seven days: there shall not be seen any thing leavened with thee, nor in all thy coasts. 8 And thou shalt tell thy son in that day, saying: This is what the Lord did to me when I came forth out of Egypt.
