'Feast of Unleavened Bread' in the Bible

And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your hosts out of the land of Egypt: therefore shall ye observe this day throughout your generations by an ordinance for ever.

Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:)

The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, in the time of the month Abib: for in the month Abib thou camest out from Egypt.
