Joshua 13: This chapter is the start of the process of distributing land to the 12 tribes of Israel. We first learn what land is still unconquered. The text then reminds us what land was already allotted by Moses before they crossed the Jordan river (east of the river).
Joshua 14: Now we get into the allotment of land west of the river. The first to get land is Caleb, of the tribe of Judah, who was one of the original 12 spies sent to Canaan by Moses in Numbers.
Joshua 15: Chapter describes in detail the borders of the land that the tribe of Judah was given. I thought this last verse was interesting: “But the people of Judah couldn’t remove the Jebusites who lived in Jerusalem. So today the Jebusites still live along with the people of Judah in Jerusalem” (Joshua 15.63; CEB study bible). According to the notes in the NRSV bible, this was here to point out that the people failed to conquer Jerusalem.
2 Thessalonians 3: Paul asks the people to pray for them as they continue doing their ministry. He also “confronts the issue of those who refuse to work and urges the readers to shun those who refuse to follow his teaching” (NRSV version, p. 2083).
