11 After the death of Joshua, the people of Israel inquired of the Lord, "Who shall go up first for us against the Canaanites, to fight against them?" 2 The Lord said, "Judah shall go up; behold, I have given the land into his hand." 3 And Judah said to Simeon his brother, "Come up with me into the territory allotted to me, that we may fight against the Canaanites. And I likewise will go with you into the territory allotted to you." So Simeon went with him. 4 Then Judah went up and the Lord gave the Canaanites and the Perizzites into their hand, and they defeated 10,000 of them at Bezek. 5 They found Adoni-bezek at Bezek and fought against him and defeated the Canaanites and the Perizzites. 6 Adoni-bezek fled, but they pursued him and caught him and cut off his thumbs and his big toes. 7 And Adoni-bezek said, "Seventy kings with their thumbs and their big toes cut off used to pick up scraps under my table. As I have done, so God has repaid me." And they brought him to Jerusalem, and he died there.
8 And the men of Judah fought against Jerusalem and captured it and struck it with the edge of the sword and set the city on fire.

(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.
