3:4 Nadab and Abihu died ⁴  before the Lord ⁵  when they offered ⁶  strange ⁷  fire ⁸  before the Lord in the wilderness of Sinai, and they had no children. ⁹  So Eleazar and Ithamar ministered as priests ¹⁰  in the presence of ¹¹  Aaron their father.

3:5 The Lord spoke to Moses: 3:6 “Bring the tribe of Levi near, ¹²  and present ¹³  them before Aaron the priest, that they may serve him. ¹⁴  3:7 They are responsible for his needs ¹⁵  and the needs of the whole community before the tent of meeting, by attending ¹⁶  to the service of the tabernacle. 3:8 And they are responsible for all the furnishings of the tent of meeting, and for the needs of the Israelites, as they serve ¹⁷  in the tabernacle. 3:9 You are to assign ¹⁸  the Levites to Aaron and his sons; they will be assigned exclusively ¹⁹  to him out of all ²⁰  the Israelites. 3:10 So you are to appoint Aaron and his sons, and they will be responsible for their priesthood; ²¹  but the unauthorized person ²²  who comes near must be put to death.”
