Exodus 12:20-22

Amplified Bible, Classic Edition

²⁰ You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread [during that week].

²¹ Then Moses called for all the elders of Israel, and said to them, Go forth, select and take a lamb according to your families and kill the Passover [lamb].

²² And you shall take a bunch of hyssop, dip it in the blood in the basin, and touch the lintel above the door and the two side posts with the blood; and none of you shall go out of his house until morning.
