Of Gershom. — Literally, to — i.e., belonging to Gershom.
Libni his son. — See Numbers 3:21, “To Gershon, the clan of the Libnite, and the clan of the Shimeite; these are the clans of the Gershonite.”
The names Jahath, Zimmah, and Zerah recur in the line of Asaph, 1 Chronicles 6:41-43 below (see the Note there). Jeaterai, in whom the present series culminates, is wholly unknown. At the time when the list was first drawn up, the name may have represented a famous chieftain or family. It has the ending of a patronymic or gentilic term, and perhaps should be read with different vowels, we ‘Ithrai, or ‘Ithri, “and the Ithrite” (comp. ‘Ishai for Yishai), a clan of which came two of David’s heroes (1 Chronicles 11:40).
