Commentary on 1 Chronicles 3:5

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on 1 Chronicles 3:1-9: 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.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on 1 Chronicles 3:5: These were all the sons of David,.... By his wives: beside the sons of the concubines; who are not reckoned, and how many they were is not known; he had ten concubines at least, Sa2 15:16 and Sa2 20:3. And Tamar their sister; not the sister of the sons of the concubines, but of his other sons, and only of Absalom by the mother's side, of whom see Sa2 13:1.

Of course Solomon was not her "only son," but he is called so (Pro 4:3) from the distinguished affection of which he was the object; and though the oldest, he is named the last of Bath-sheba's children.
