Exodus 12:20-22

Common English Bible

²⁰ You should not eat anything made with yeast in all your settlements. You should eat only unleavened bread.”

²¹ Then Moses called together all of Israel’s elders and said to them, “Go pick out one of the flock for your families, and slaughter the Passover lamb. ²² Take a bunch of hyssop, dip it into the blood that is in the bowl, and touch the beam above the door and the two doorposts with the blood in the bowl. None of you should go out the door of your house until morning.
