(15) The sonsof Moses.--See Exodus 2:22 for "Gershom," Exodus 18:3-4 for both. Gershom means "expulsion" (comp Genesis 3:24), and is a variant form of Gcrshon. What is said in Exodus 2:22 is an allusive play on the name, not a derivation of it. "Eliezer," God is help, a distinct name from "Eleazar" (1 Chronicles 23:22), God hath helped, or, is a helper.
23:1-23 David, having given charge concerning the building of the temple, settles the method of the temple service, and orders the officers of it. When those of the same family were employed together, it would engage them to love and assist one another.
