Matthew Henry Presbyterian @wholebiblehenry

We had an account of David's sons, Sa2 3:2, etc., and Sa2 5:14, etc. 1. He had many sons; and no doubt wrote as he thought, Psa 127:5. Happy is the man that hath his quiver full of these arrows. 2.

Jamieson-Fausset-Brown Reformed @jfbcommentary

Elishama and Eliphelet--Two sons of the same name are twice mentioned (Ch1 3:8). They were the children of different mothers, and had probably some title or epithet appended by which the one was distinguished from the other. Or, it might be, that the former two were dead, and their names had been given to sons afterwards born to preserve their memories.

Geneva Bible Notes Reformed @genevanotes

Ibhar also, and Elishama, and Eliphelet, (d) Elishama, or Elishua, and Eliphelet died, and David named those sons who were born next by the same names; in the book of kings his living children are mentioned and here both they that were alive and dead.
