Exodus 12:17-19

Amplified Bible, Classic Edition

¹⁷ And you shall observe the Feast of Unleavened Bread, for on this very day have I brought your hosts out of the land of Egypt; therefore shall you observe this day throughout your generations as an ordinance forever.

¹⁸ 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.

¹⁹ Seven days no leaven [symbolic of corruption] shall be found in your houses; whoever eats what is leavened shall be excluded from the congregation of Israel, whether a stranger or native-born.^(A)
