'Sons of Levi' in the Bible

“Number the sons of Levi by their fathers’ households, by their families (clans). You shall number every male from a month old and upward.”

These are the [three] sons of Levi by their names: Gershon, Kohath, and Merari.

“Take a census of the sons of Kohath from among the sons of Levi, by their families (clans), by their fathers’ households,

then put fire in them and place incense on them in the presence of the Lord tomorrow; and the man whom the Lord chooses shall be the one who is holy. You have gone far enough, you sons of Levi.”

Then Moses said to Korah, “Hear now, you sons of Levi,

and that He has brought you near [to Him], Korah and all your brothers, sons of Levi with you? Would you seek the priesthood also?
