³ The children of Amram were Aaron, Moses, and Miriam.

The sons of Aaron were Nadab, Abihu, Eleazar, and Ithamar.

The Sin of Nadab and Abihu

10 Aaron’s sons Nadab and Abihu put coals of fire in their incense burners and sprinkled incense over them. In this way, they disobeyed the Lord by burning before him the wrong kind of fire, different than he had commanded.

²⁰ Amram married his father’s sister Jochebed, and she gave birth to his sons, Aaron and Moses. (Amram lived to be 137 years old.)

¹² Then Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take what is left of the grain offering after a portion has been presented as a special gift to the Lord, and eat it beside the altar. Make sure it contains no yeast, for it is most holy.

²⁰ Then Miriam the prophet, Aaron’s sister, took a tambourine and led all the women as they played their tambourines and danced.

Duties of the Priests

24 This is how Aaron’s descendants, the priests, were divided into groups for service. The sons of Aaron were Nadab, Abihu, Eleazar, and Ithamar. ² But Nadab and Abihu died before their father, and they had no sons. So only Eleazar and Ithamar were left to carry on as priests.

³ With the help of Zadok, who was a descendant of Eleazar, and of Ahimelech, who was a descendant of Ithamar, David divided Aaron’s descendants into groups according to their various duties. ⁴ Eleazar’s descendants were divided into sixteen groups and Ithamar’s into eight, for there were more family leaders among the descendants of Eleazar.

⁵ All tasks were assigned to the various groups by means of sacred lots so that no preference would be shown, for there were many qualified officials serving God in the sanctuary from among the descendants of both Eleazar and Ithamar. ⁶ Shemaiah son of Nethanel, a Levite, acted as secretary and wrote down the names and assignments in the presence of the king, the officials, Zadok the priest, Ahimelech son of Abiathar, and the family leaders of the priests and Levites. The descendants of Eleazar and Ithamar took turns casting lots.

¹³ The sons of Amram were Aaron and Moses. Aaron and his descendants were set apart to dedicate the most holy things, to offer sacrifices in the Lord’s presence, to serve the Lord, and to pronounce blessings in his name forever.

¹⁶ Moses then asked them what had happened to the goat of the sin offering. When he discovered it had been burned up, he became very angry with Eleazar and Ithamar, Aaron’s remaining sons.

Clothing for the Priests

28 “Call for your brother, Aaron, and his sons, Nadab, Abihu, Eleazar, and Ithamar. Set them apart from the rest of the people of Israel so they may minister to me and be my priests.
