Exodus 12:19-21

Expanded Bible

¹⁹ For seven days there must not be any ·yeast [leaven] in your houses. Anybody who eats ·yeast [something leavened] during this time, either an ·Israelite [^Lnative citizen in the land] or ·non-Israelite [^Lalien; sojourner], must be cut off from the ·community [congregation; assembly] of Israel. ²⁰ During this feast you must not eat anything ·made with yeast [leavened]. You must eat only ·bread made without yeast [unleavened bread] wherever you live.”

²¹ Then Moses called all the elders of Israel together and told them, “·Get the animals [^LGo, select/separate lambs] for your families and ·kill [slaughter] the lamb for the Passover.
