||Nadav and Avihu died before God when they offered unauthorized fire to God in the Sinai Desert. They had no children. Thus, [only] Eleazar and Ithamar served as priests during their father Aaron's lifetime.
Vayamot Nadav va'Avihu lifney Adonay behakrivam esh zarah lifney Adonay bemidbar Sinay uvanim lo-hayu lahem vayechahen El'azar ve'Itamar al-peney Aharon avihem.
||God spoke to Moses, saying:
Vayedaber Adonay el-Moshe lemor.
||Bring forth the tribe of Levi, and present it to Aaron the priest, so that [its members] shall serve him.
Hakrev et-mateh Levi veha'amadeta oto lifney Aharon hakohen veshertu oto.
