(Jdg 1:1-8) Proceedings of the tribes of Judah and Simeon.
(Jdg 1:9-20) Hebron and other cities taken.
(v. 21-36) The proceedings of other tribes.
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.
The Canaanites had iron chariots; but Israel had God on their side, whose chariots are thousands of angels, Psa 68:17. Yet they suffered their fears to prevail against their faith. About Caleb we read in Jos 15:16-19. The Kenites had settled in the land. Israel let them fix where they pleased, being a quiet, contented people. They that molested none, were molested by none. Blessed are the meek, for they shall inherit the earth.
The people of Israel were very careless of their duty and interest. Owing to slothfulness and cowardice, they would not be at the pains to complete their conquests. It was also owing to their covetousness: they were willing to let the Canaanites live among them, that they might make advantage of them. They had not the dread and detestation of idolatry they ought to have had. The same unbelief that kept their fathers forty years out of Canaan, kept them now out of the full possession of it. Distrust of the power and promise of God deprived them of advantages, and brought them into troubles. Thus many a believer who begins well is hindered. His graces languish, his lusts revive, Satan plies him with suitable temptations, the world recovers its hold; he brings guilt into his conscience, anguish into his heart, discredit on his character, and reproach on the gospel. Though he may have sharp rebukes, and be so recovered that he does not perish, yet he will have deeply to lament his folly through his remaining days; and upon his dying bed to mourn over the opportunities of glorifying God and serving the church he has lost. We can have no fellowship with the enemies of God within us or around us, but to our hurt; therefore our only wisdom is to maintain unceasing war against them.
