Here is, I. The family of Jacob. His twelve sons are here named, that illustrious number so often celebrated almost throughout the whole Bible, from the first to the last book of it. At every turn we meet with the twelve tribes that descended from these twelve patriarchs. The personal character of several of them was none of the best (the first four were much blemished), and yet the covenant was entailed on their seed; for it was of grace, free grace, that it was said, Jacob have I loved - not of works, lest any man should boast.

II.The family of Judah. That tribe was most praised, most increased, and most dignified, of any of the tribes, and therefore the genealogy of it is the first and largest of them all. In the account here given of the first branches of that illustrious tree, of which Christ was to be the top branch, we meet, 1. With some that were very bad. Here is Er, Judah's eldest son, that was evil in the sight of the Lord, and was cut off, in the beginning of his days, by a stroke of divine vengeance: The Lord slew him, Ch1 2:3. His next brother, Onan, was no better, and fared no better. Here is Tamar, with whom Judah, her father-in-law, committed incest, Ch1 2:4. And here is Achan, called Achar - a troubler, that troubled Israel by taking of the accursed thing, Ch1 2:7. Note, The best and most honourable families may have those belonging to them that are blemishes. 2. With some that were very wise and good, as Heman and Ethan, Calcol and Dara, who were not perhaps the immediate sons of Zerah, but descendants from him, and are named because they were the glory of their father's house; for, when the Holy Ghost would magnify the wisdom of Solomon, he declares him wiser than these four men, who, though the sons of Mahol, are called Ezrahites, from Zerah, Kg1 4:31. That four brothers should be eminent for wisdom and grace was a rare thing. 3. With some that were very great, as Nahshon, who was prince of the tribe of Judah when the camp of Israel was formed in the wilderness, and so led the van in that glorious march, and Salman, or Salmon, who was in that post of honour when they entered into Canaan, Ch1 2:10, Ch1 2:11.

III.The family of Jesse, of which a particularly account is kept for the sake of David, and the Son of David, who is a rod out of the stem of Jesse, Isa 11:1. Hence it appears that David was a seventh son, and that his three great commanders, Joab, Abishai, and Asahel, were the sons of one of his sisters, and Amasa of another. Three of the four went down slain to the pit, though they were the terror of the mighty.

Jether the Ishmeelite - "They called him Jether, because he girded himself with his sword, that he might assist David with the Arabians, when Abner was endeavoring to destroy David and the whole race of Jesse, as being unfit to enter into the congregation of the Lord, on account of Ruth the Moabitess." - T.

And Segub begat Jair, who had twenty three cities in the land of Gilead. Which, according to Kimchi, he inherited in right of his wife, which, he says, he took out of the land of Gilead; but they seem to be rather what he took by force of arms from the former inhabitants; see Num 32:41.

1 Chronicles 2:23

ch1 2:23

ch1 2:23

ch1 2:23And he took Geshur, and Aram, with the towns of Jair, from them,.... Cities or countries which the Geshurites and Aramaeans, or Syrians, before inhabited; and which he took from them, together with other towns, which, being taken by him, were called after his name; the Targum is, the Geshurites and Aramaeans took the villages of Jair from them; that is, from the sons of Jair in later times; see Jos 12:5.

with Kenath, and the towns thereof; which Jair took by Nobah his general, and called it after his name, Num 32:42, even sixty cities; see Deu 3:4.

all these belonged to the sons of Machir the father of Gilead: being given him by Moses, Num 32:40.

Jether the Ishmaelite--(compare Sa2 17:25). In that passage he is called Ithra an Israelite; and there seems no reason why, in the early days of David, anyone should be specially distinguished as an Israelite. The presumption is in favor of the reading followed by the Septuagint, which calls him "Jetra the Jezreelite." The circumstance of his settling in another tribe, or of a woman marrying out of her own tribe, was sufficiently rare and singular to call for the statement that Abigail was married to a man of Jezreel.
