Judges 1:2; Judges 1:3

2 The LORD answered, “Judah shall go up; I have given the land into their hands.”

3 The men of Judah then said to the Simeonites their fellow Israelites, “Come up with us into the territory allotted to us, to fight against the Canaanites. We in turn will go with you into yours.” So the Simeonites went with them.
