'Eat Unleavened Bread' in the Bible

"'Seven days you shall eat unleavened bread; even the first day you shall put away yeast out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, until the twenty first day of the month at evening.

You shall eat nothing leavened. In all your habitations you shall eat unleavened bread.'"

Seven days you shall eat unleavened bread, and in the seventh day shall be a feast to Yahweh.

You shall observe the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib (for in it you came out from Egypt), and no one shall appear before me empty.

"You shall keep the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib; for in the month Abib you came out from Egypt.
