'Eat Unleavened Bread' in the Bible

[In the celebration of the Passover in future years,] seven days you shall eat unleavened bread, but on the first day you shall remove the leaven from your houses [because it represents the spread of sin]; for whoever eats leavened bread on the first day through the seventh day, that person shall be cut off and excluded from [the atonement made for] Israel.

In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, [and continue] until the twenty-first day of the month at evening.

You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread.’”

For seven days you shall eat unleavened bread, and on the seventh day there shall be a feast to the Lord.

You shall observe the Feast of Unleavened Bread; for seven days you shall eat unleavened bread, as I commanded you, at the appointed time in the month of Abib, for in it you came out of Egypt. No one shall appear before Me empty-handed [but you shall bring sacrificial offerings].

“You shall observe the Feast of Unleavened Bread (Passover). For seven days you shall eat unleavened bread, as I have commanded you, at the appointed time in the month of Abib; for in the month of Abib you came out of Egypt.
