Numbers 3:18, 21, 24

And these are the names of the sons of Gershon by their families: Libni and Shimei.

From Gershon came the family of the Libnites and the family of the Shimites; these were the families of the Gershonites.

And the leader of the father’s house of the Gershonites was Eliasaph the son of Lael.
