The chapter opens with the twelve sons of Israel, from Reuben to Benjamin, and quickly concentrates on Judah. It recalls that Er, his firstborn, was wicked in the Lord's sight and that the Lord put him to death, and that Tamar, Judah's daughter-in-law, bore Perez and Zerah. It also mentions Achar, who brought trouble on Israel by breaking what was devoted to God.
The main line runs through Perez, Hezron, Ram, Amminadab and Nahshon, down to Salmon, Boaz, Obed and Jesse. In this way the author links Boaz and Obed to the story of Ruth, though without telling it. This chapter names seven sons of Jesse, and David was the seventh; his sisters Zeruiah and Abigail are named too, the mothers of Joab, Abishai and Asahel, three of David's best-known warriors.
The rest of the chapter follows other descendants of Hezron, above all the families of Jerahmeel and Caleb, with their towns and clan names. Among them are curious details, such as a man who had no sons and gave his daughter in marriage to an Egyptian servant. The chapter ends with the clans of scribes who lived at Jabez and with the Kenites, from whom the Rechabites came.
