'Sons of Levi' in the Bible
“Number the sons of Levi by their fathers’ households, by their families; every male from a month old and upward you shall number.”
These then are the sons of Levi by their names: Gershon and Kohath and Merari.
“Take a census of the descendants of Kohath from among the sons of Levi, by their families, by their fathers’ households,
and put fire in them, and lay incense upon 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!”
and that He has brought you near, Korah, and all your brothers, sons of Levi, with you? And are you seeking for the priesthood also?
“To the sons of Levi, behold, I have given all the tithe in Israel for an inheritance, in return for their service which they perform, the service of the tent of meeting.
