3 The men of Judah said to their relatives from the tribe of Simeon, "Join with us to fight against the Canaanites living in the territory allotted to us. Then we will help you conquer your territory." So the men of Simeon went with Judah. 4 When the men of Judah attacked, the Lord gave them victory over the Canaanites and Perizzites, and they killed 10,000 enemy warriors at the town of Bezek. 5 While at Bezek they encountered King Adoni-bezek and fought against him, and the Canaanites and Perizzites were defeated. 6 Adoni-bezek escaped, but the Israelites soon captured him and cut off his thumbs and big toes. 7 Adoni-bezek said, "I once had seventy kings with their thumbs and big toes cut off, eating scraps from under my table. Now God has paid me back for what I did to them." They took him to Jerusalem, and he died there.

Commentary on Judges 1:1-8
(Read Judges 1:1-8)
The Israelites were convinced that the war against the Canaanites was to be continued; but they were in doubt as to the manner in which it was to be carried on after the death of Joshua. In these respects they inquired of the Lord. God appoints service according to the strength he has given. From those who are most able, most work is expected. Judah was first in dignity, and must be first in duty. Judah's service will not avail unless God give success; but God will not give the success, unless Judah applies to the service. Judah was the most considerable of all the tribes, and Simeon the least; yet Judah begs Simeon's friendship, and prays for aid from him. It becomes Israelites to help one another against Canaanites; and all Christians, even those of different tribes, should strengthen one another. Those who thus help one another in love, have reason to hope that God will graciously help both. Adoni-bezek was taken prisoner. This prince had been a severe tyrant. The Israelites, doubtless under the Divine direction, made him suffer what he had done to others; and his own conscience confessed that he was justly treated as he had treated others. Thus the righteous God sometimes, in his providence, makes the punishment answer the sin.
