And bring near to yourself Aaron, your brother, and his sons with him from among the Israelites, so that they may minister to Me as priests —Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.
Now Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it, and put incense on it, and offered strange fire before the Lord, which He did not command them to do.
Moses spoke to Aaron, and to Eleazar and Ithamar, his sons who were left: Take the grain offering that remains of the food offerings of the Lord made by fire, and eat it without leaven beside the altar, for it is most holy.
