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. Some of them were a grief to him, as Amnon, Absalom, and Adonijah; and we do not read of any of them that imitated his piety or devotion except Solomon, and he came far short of it. 3. One of them, which Bath-sheba bore to him, he called Nathan, probably in honour of Nathan the prophet, who reproved him for his sin in that matter and was instrumental to bring him to repentance. It seems he loved him the better for it as long as he lived. It is wisdom to esteem those our best friends that deal faithfully with us. From this son of David our Lord Jesus descended, as appears Luk 3:31. 4. Here are two Elishamas, and two Eliphelets, Ch1 3:6, Ch1 3:8. Probably the two former were dead, and therefore David called two more by their names, which he would not have done if there had been any ill omen in this practice as some fancy. 5. David had many concubines; but their children are not named, as not worthy of the honour (Ch1 3:9), the rather because the concubines had dealt treacherously with David in the affair of Absalom. 6. Of all David's sons Solomon was chosen to succeed him, perhaps not for any personal merits (his wisdom was God's gift), but so, Father, because it seemed good unto thee.

By Eglah his wide - The Targum, Jarchi, and others, maintain that this was Michal, the daughter of Saul; but this does not well agree with Sa2 6:23 : Michal had no child to the day of her death. Yet she might have had a child before the time that is mentioned above.

Now these were the sons of David,.... The six following born in Hebron, who are reckoned in the same order as in Sa2 3:2, only here the second son is called Daniel, who there goes by the name of Chileab; he had two names, the reason of which see there; and here David's wife, Eglah, is said in the Targum to be Michal, Saul's daughter; see Gill on Sa2 3:5, to which is added an account of his reign both in Hebron and Jerusalem, agreeably to Sa2 5:5.

1 Chronicles 3:5

ch1 3:5
ch1 3:5
ch1 3:5And these were born unto him in Jerusalem,.... Whose names follow, in all nine; there are but seven mentioned in Sa2 5:14 the reason of which see in the notes there; See Gill on Sa2 5:14. See Gill on Sa2 5:15. See Gill on Sa2 5:16. it may be observed that Bathsheba is here called Bathshua, and her father Ammiel, whose name is Eliam in Sa2 11:3, names of much the same signification.

Eglah his wife--supposed to be another name of Michal, who, though she had no son after her mockery of David for dancing before the ark [Sa2 6:16, Sa2 6:20], might have had one previous to that time. She has the title of wife appended to her name because she was his proper wife; and the mention of her name last probably arose from the circumstance that, having been withdrawn from David and married to another husband but afterwards restored, she had in reality become the last of his wives.
