Charles Ellicott Commentary 1 Chronicles 3:6

"and Ibhar, and Elishama, and Eliphelet," — 1 Chronicles 3:6 (ASV)

Ibhar. — "He" (that is, God) "chooses."

Elishama. — Spelled Elishua in both of the parallel passages. (See Note on 1 Chronicles 3:5.) The recurrence of Elishama ("God hears") in 1 Chronicles 3:8 is no argument against the name here.

Eliphelet ("God is deliverance") also occurs twice, and David may have chosen to give names so expressive of his own particular faith and trust to the sons of different wives. (Psalms 18:6.) This Eliphelet (called Elphalet—Hebrew, Elpèlet, 1 Chronicles 14:5; a by-form, as Abram is of Abiram, Absalom of Abishalom, or Abshai of Abishai) is omitted in Samuel.

Nogah (meaning brightness—that is, of the Divine Presence, Psalms 18:13—a hymn that is certainly David’s) is also omitted in Samuel. (Compare Japhia, "the Shining One.") Nepheg means "shoot, scion."
