Judges 1:1-4

Now it came about after the death of Joshua, that the sons (descendants) of Israel (Jacob) asked the LORD, “Who shall go up first for us against the Canaanites, to fight against them?” And the LORD said, “Judah shall go up [first]; behold, I have given the land into his hand.” And [the tribe of the sons of] Judah said to [the tribe of the sons of] Simeon his brother, “Come up with me into my allotted territory, so that we may fight against the Canaanites; and I likewise will go with you into your allotted territory.” So Simeon went with him. Then Judah went up, and the LORD gave the Canaanites and the Perizzites into their hand, and they struck down in defeat ten thousand men at Bezek.
