1 Chronicles 23:17

And the sons of Eliezer were, Rehabiah the chief. — The word “were” (became) ought not to be in italics in the text, as it is expressed in the Hebrew.

The chief (head) means founder and eponym of the clan the sons of Rehabiah.

And Eliezer had none other sons. — Literally, And there became not to Eliezer ether sons, and the sons of Rehabiah had multiplied exceedingly (unto height, 1 Chronicles 22:5). The clan Rehabiah was very populous.

Thus (1 Chronicles 23:16) the descendants of Moses were comprised in two father-houses, or clans, viz., Shebuel and Rehabiah.
