Numbers 3:16 DBY

¹⁴  And Jehovah spoke to Moses in the wilderness of Sinai, saying,

¹⁵  Number the sons of Levi according to their fathers' houses, after their families; every male from a month old and upward shalt thou number them.

¹⁶  And Moses numbered them, according to the commandment of Jehovah, -- as he had been commanded.

¹⁷  And these are the sons of Levi by their names: Gershon, and Kohath, and Merari.

¹⁸  And these are the names of the sons of Gershon according to their families: Libni and Shimei.
