1 Chronicles 2:9

“The sons also of Hezron, that were born unto him, etc.] The Targum adds, in Timnath; but most likely in Egypt: Jerahmeel, and Ram, and Chelubai; afterwards called Caleb. Ver. 10-12. And Ram begat Amminadab, etc.] Ram is the same with Aram, (<400103>Matthew 1:3,4) the genealogy is carried down from him to Jesse in the same order as there, and in (<080419>Ruth 4:19-22) only here Nahshon the son of Amminadab is called the prince of the children of Judah; which Kimchi and Jarchi say is written for the honour of David, who descended from him; and Salmon his son is here called Salma. Ver. 13-15. And Jesse begat his firstborn Eliab, and Abinadab the second, and Shimma the third, Nathanael the…”

Ruth 4:18-22), the other descendants of Hezron (1 Chr 2:18-41), then the descendants of Hezron’s son Caleb (2:42-55). 2:9 Caleb was the most notable immediate descendant of Hezron, so the author covers his descendants in detail (2:42-55). This Caleb was apparently not the same individual as Caleb son of Jephunneh, a descendant of Kenaz (see study note on 4:13-15).”

“The only name given here as that of a descendant of Ethan is Azariah, of whom nothing further is known, while the name recurs frequently. Nothing more is said of the remaining sons of Zerah; they are merely set down as famous men of antiquity (Berth.). There follows in 1 Chronicles 2:9-41 The family of Hezron, the first-born son of Pharez, which branches off in three lines, originating with his three sons respectively. The three sons of Hezron are Jerahmeel, and Ram, and Chelubai; but the families springing from them are enumerated in a different order. First ( Ch1 2:10-17) we have the family of Ram, because King David is descended from him; then ( Ch1 2:18-24) the family of Chelubai or…”
