1. When the Lord talked with Moses on Mount Sinai,
10. who have been appointed to be priests. Anyone else who tries to perform the duties of a priest must be put to death.
11-13. Moses, I have chosen these Levites from all Israel, and they will belong to me in a special way. When I killed the firstborn sons of the Egyptians, I decided that the firstborn sons in every Israelite family and the firstborn males of their flocks and herds would be mine. But now I accept these Levites in place of the firstborn sons of the Israelites.
