²¹ Then Moses called the leaders of the Israelites to come to him. He said to them, ‘Go immediately and choose a lamb for each of your families. Then kill the animals for the Passover feast. ²² Put the blood into a dish. Then take a branch of hyssop.^[a] Make it wet with the blood that is in the dish. Then put some of the blood on the wood that is round your door. Nobody must go out of the door of his house until the morning. ²³ The Lord will pass through the country and he will kill the Egyptians. But when the Lord sees the blood on the wood round the door, he will pass over that house. He will not let the death angel come into your houses. The Lord will not let him kill you.

²⁴ You must obey these rules always, both you and your descendants, for all time. ²⁵ You will go into the land that the Lord promised to give you. Then you must continue to obey these rules. ²⁶ Your children may say to you, “What does this feast mean?” ²⁷ Then you must say to them, “It is the Lord's Passover sacrifice. The Lord passed over the houses of the Israelites when they were in Egypt. He killed the Egyptians but he saved our families.” ’ Then the people bent their heads down to the ground and they worshipped God.
