Book of Judges
In the opening words of the Book of Judges, following the death of Joshua, the Israelites "asked the Lord" which tribe should be first to go to occupy its allotted territory, and the tribe of Judah was identified as the first tribe. According to the narrative in the Book of Judges, the tribe of Judah invited the tribe of Simeon to fight with them in alliance to secure each of their allotted territories. As is the case with Joshua, most scholars do not believe that the book of Judges contains reliable history.
