Richter 1:3

Judah invited Simeon his brother, i.e., their brother tribe, to take part in the contest. The epithet is applied to Simeon, not because Simeon and Judah, the sons of Jacob, were the children of the same mother, Leah (Gen 29:33, Gen 29:35), but because Simeon's inheritance was within the territory of Judah (Jos 19:1.), so that Simeon was more closely connected with Judah than any of the other tribes. "Come up with me into my lot (into the inheritance that has fallen to me by lot), that we may fight against the Canaanites, and I likewise will go with thee into thy lot. So Simeon went with him," i.e., joined with Judah in making war upon the Canaanites. This request shows that Judah's principal intention was to make war upon and exterminate the Canaanites who remained in his own and Simeon's inheritance. The different expressions employed, come up and go, are to be explained from the simple fact that the whole of Simeon's territory was in the shephelah and Negeb, whereas Judah had received the heart of his possessions upon the mountains.

This chapter gives us a particular account what sort of progress the several tribes of Israel made in the reducing of Canaan after the death of Joshua. He did (as we say) break the neck of that great work, and put it into such a posture that they might easily have perfected it in due time, if they had not been wanting to themselves; what they did in order hereunto, and wherein they came short, we are told. I. The united tribes o Judah and Simeon did bravely. 1. God appointed Judah to begin (Jdg 1:1, Jdg 1:2). 2. Judah took Simeon to act in conjunction with him (Jdg 1:3). 3. They succeeded in their enterprises against Bezek (Jdg 1:4-7), Jerusalem (Jdg 1:8). Hebron and Debir (Jdg 1:9-15), Hormah, Gaza, and other places (Jdg 1:17-19). 4. Yet where there were chariots of iron their hearts failed them (Jdg 1:19). Mention is made of the Kenites settling among them (Jdg 1:16). II. The other tribes, in comparison with these, acted a cowardly part. 1. Benjamin failed (Jdg 1:21). 2. The house of Joseph did well against Beth-el (Jdg 1:22-26), but in other places did not improve their advantages, nor Manasseh (Jdg 1:27, Jdg 1:28), nor Ephraim (Jdg 1:29). 3. Zebulun spared the Canaanites (Jdg 1:30). 4. Asher truckled worse than any of them to the Canaanites (Jdg 1:31, Jdg 1:32). 5. Naphtali was kept out of the full possession of several of his cities (Jdg 1:33). 6. Dan was straitened by the Amorites (Jdg 1:34). No account is given of Issachar, nor of the two tribes and a half on the other side Jordan.
