1:21-36 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.
And when he showed them the entrance, into the city,.... Pointing to it with his fingers, as the same writers observe:
they smote the city with the edge of the sword; they gave notice of what intelligence they had got to the body of the army, who came up, entered the city, took it, and put the inhabitants of it to the sword, as they were ordered to do with all the Canaanites:
but they let go the man and all his family; who had returned to it, encouraged by the promise made him, and for the sake of saving of his family; which though not expressed, he might have asked the favour of sparing them, which might be promised, as was in the case of Rahab; provided he would either renounce Heathenism, and embrace the true religion, or depart to another country, the latter of which he chose.
