The chapter runs through several branches of Judah: Perez, Hezron, Carmi, Hur and Shobal, and the clans that came from them, among which families of potters and linen workers are mentioned. Othniel, son of Kenaz, and Caleb are named too, and a valley of craftsmen is recalled. It is a record of people who lived by specific trades and served the king.
In the middle of that list the author stops at Jabez. His mother gave him that name because she bore him in pain, but the text says he was more honorable than his brothers. Jabez called on the God of Israel and asked him to bless him, enlarge his territory, be with him and keep him from harm so that he would not suffer pain. God granted what he asked.
The second part of the chapter concerns the tribe of Simeon, whose land lay inside Judah. Its families are listed, and we are told that some of them went to look for pasture toward Gedor and found a land that was good, wide and quiet, occupied by descendants of Ham. In the days of Hezekiah they took that place, and other Simeonites went to Mount Seir, where they defeated the remnant of the Amalekites and settled.
