Joshua 15 deals with the land allotment given to the largest tribe, Judah. Judah receives the southernmost extension of the Promised Land. It includes the city of the Jebusites, unconquered for now (vs. 63). The city will eventually fall to David and become Jerusalem. Later on, when a civil war will divide the tribes, the tribes of Judah and Benjamin will form the southern kingdom known as Judah, later called Judea in the New Testament era.
