Numbers 3:15-17

Amplified Bible

¹⁵ “Number the sons of Levi by their fathers’ households, by their families (clans). You shall number every male from a month old and upward.” ¹⁶ So Moses numbered them just as he was commanded by the word (mouth) of the Lord. ¹⁷ These are the [three] sons of Levi by their names: Gershon, Kohath, and Merari.
