Numbers 3:5-13

The Levites help the priests

5 Then the Lord said to Moses, 6 ‘Bring the tribe of Levi to Aaron the priest. They must help him. 7 They must serve him and all the Israelites. They must work at the Tent of Meeting and take care of it. 8 They must work on behalf of the Israelites. They must take care of the things that are in the Tent of Meeting. That is how they will serve God. 9 Give the Levites to Aaron and to his descendants. They will be the Israelites who help him. They do not have to do anything else. 10 But you must make a list of Aaron and his descendants. They will be the priests. If any other person comes near to the special Tent, they must die.’

11 The Lord also said to Moses, 12 ‘I will not take the firstborn son of every woman in Israel to belong to me. I will take the Levites instead of them. 13 I killed all the firstborn sons of the Egyptians, but I did not kill the firstborn sons of the Israelites. As a result, the firstborn son of every person and animal among the Israelites became mine. They belong to me. I am the Lord!’
