New Defender's Study Bible Notes
2:1 the sons of Israel. I Chronicles 2–8 give the descendants of the sons of Jacob, beginning not with Reuben but with Judah. However, for reasons not stated, the genealogies of Dan and Zebulun were not included. Both of these are listed in the divisions of the land in the future millennial age (Ezekiel 48:1,26).
2:6 Ethan, and Heman, and Calcol, and Dara. These four descendants of Zerah (probably not his immediate sons) became noted as musicians and sages (I Kings 4:31).
2:7 Achar. This is the same as Achan, whose greed caused great trouble for Joshua and the Israelites at Jericho (Joshua 7:18-24).
2:10 Nahshon. Nahshon was “prince of the children of Judah” during the early part of the wilderness period (Numbers 1:7; 7:12).
2:16 Abigail. Another of David’s sisters, Abigail, was the mother of Amasa, who became Absalom’s general when Absalom rebelled against David. See II Samuel 17:25. However, Abigail was only a half-sister to David. Amasa’s father Jether is called both an Israelite and an Ishmaelite, indicating either that he was of mixed parentage or else that he was an Ishmaelite proselyte to Israel’s faith.
2:16 three. It is noteworthy that three of David’s most conspicuous generals were his own nephews. Abishai, Joab and Asahel were all sons of his sister Zeruiah. Note II Samuel 2:18.
2:18 Caleb the son of Hezron. This Caleb (same as Chelubai in I Chronicles 2:9) is probably not the same Caleb as the companion of Joshua who had served as one of the twelve spies and who later was a hero of the conquest. The father of that Caleb was “Jephunneh the Kenezite” (Joshua 14:6). Still another Caleb is mentioned in I Chronicles 2:50.
2:55 families of the scribes. Evidently the scribes, whose duties included copying the Scriptures, were organized in “families,” or groups, in order to help insure accuracy of copying.
