Exodus 12:17-19

Douay-Rheims 1899 American Edition

¹⁷ And you shall observe the feast of the unleavened bread: for in this same day I will bring forth your army out of the land of Egypt, and you shall keep this day in your generations by a perpetual observance.

¹⁸ The first month, the fourteenth day of the month in the evening, you shall eat unleavened bread, until the one and twentieth day of the same month in the evening.

¹⁹ Seven days there shall not be found any leaven in your houses: he that shall eat leavened bread, his soul shall perish out of the assembly of Israel, whether he be a stranger or born in the land.
