JDG 1:3

3 The men of Judah went to their fellow Israelis, [the men] from the tribe of Simeon, and said to them, “Come and help us to fight the Canaan people-group [in order that we can take from them] the land [that Yahweh] allotted to us. If you do that, we will go with you [and help you] conquer the people in the land [that Yahweh promised to give to] you.” So the men from the tribe of Simeon went with the men of the tribe of Judah.
