You shall dress them with belts, Aharon and his sons, and bind headbands on them: and they shall have the priesthood by a perpetual statute: and you shall consecrate Aharon and his sons.
Moshe spoke to Aharon, and to El`azar and to Itamar, his sons who were left, *Take the meal offering that remains of the offerings of the LORD made by fire, and eat it without yeast beside the altar; for it is most holy;
You and your sons with you shall keep your priesthood for everything of the altar, and for that within the veil; and you shall serve: I give you the priesthood as a service of gift: and the stranger who comes near shall be put to death.
Nadav and Avihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children. El`azar and Itamar ministered in the Kohen's office in the presence of Aharon their father.
