| Clarke's Commentary on the Bible Nine - There are thirteen if we count the four sons of Bath-sheba, and nine without them; and in the second book of Samuel there are eleven, reckoning the above four, and without them only seven. In the book of Samuel probably only those who were alive were reckoned, while the author of the Chronicles comprises those also who were dead in this enumeration. Jarchi supposes that the duplicate Elishama and Eliphelet are those which increase the regular number seven to nine; and that the dead without posterity, as well as the living, are mentioned to increase the number of David's descendants; for, says he, the whole book is written for the honor of David and his seed.

Wesley's Notes 3:8 Nine - There are but seven mentioned, 2Sam 5:14. Two of them are omitted there, because they died very early, and here we have all the sons of David, which clause is not added 2Sam 5:13 - 16.

Jamieson-Fausset-Brown Bible Commentary8. nine-The number of David's sons born after his removal to Jerusalem, was eleven (2Sa 5:14), but only nine are mentioned here: two of them being omitted, either in consequence of their early deaths or because they left no issue.
Matthew Henry's Concise Commentary3:1-24 Genealogies. - Of all the families of Israel, none were so illustrious as the family of David: here we have a full account of it. From this family, as concerning the flesh, Christ came. The attentive observer will perceive that the children of the righteous enjoy many advantages.
Matthew Henry's Whole Bible CommentaryChapter 3 Of all the families of Israel none was so illustrious as the family of David. That is the family which was mentioned in the foregoing chapter (v. 15). Here we have a full account of it. I. David's sons (v. 1-9). II. His successors in the throne as long as the kingdom continued (v. 10-16). III. The remains of his family in and after the captivity (v. 17-24). From this family, "as concerning the flesh, Christ came." Verses 1-9 We had an account of David's sons, 2 Sa. 3:2, etc., and 5:14, etc. 1. He had many sons; and no doubt wrote as he thought, Ps. 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 Lu. 3:31. 4. Here are two Elishamas, and two Eliphelets, v. 6, 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 (v. 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. |
