And you shall take to yourself Aaron your brother, and his sons with him, from among the sons of Israel, so that he may minister to Me in the priest's office: Aaron and Aaron's sons, Nadab and Abihu, Eleazar and Ithamar.
And 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 Jehovah, which He had not commanded them.
And Moses spoke to Aaron, and to Eleazar and to Ithamar, his sons that were left, Take the food offering that remains of the offerings of Jehovah made by fire, and eat it without leaven beside the altar. For it is most holy.
