II. He informs him of the true and only cause of this disaster, and shows him wherefore he contended with them (v. 11): Israel hath sinned. "Think not that God's mind is changed, his arm shortened, or his promise about to fail; no, it is sin, it is sin, that great mischief-maker, that has stopped the current of divine favours and has made this breach upon you." The sinner is not named, though the sin is described, but it is spoken of as the act of Israel in general, till they have fastened it upon the particular person, and their godly sorrow have so wrought a clearing of themselves, as theirs did, 2 Cor. vii. 11. Observe how the sin is here made to appear exceedingly sinful. 1. They have transgressed my covenant, an express precept with a penalty annexed to it. It was agreed that God should have all the spoil of Jericho, and they should have the spoil of the rest of the cities of Canaan; but, in robbing God of his part, they transgressed this covenant. 2. They have even taken of the devoted thing, in contempt of the curse which was so solemnly denounced against him that should dare to break in upon God's property, as if that curse had nothing in it formidable. 3. They have also stolen; they did it clandestinely, as if they could conceal it from the divine omniscience, and they were ready to say, The Lord shall not see, or will not miss so small a matter out of so great a spoil. Thus thou thoughtest I was altogether such a one as thyself. 4. They have dissembled also. Probably, when the action was over, Joshua called all the tribes, and asked them whether they had faithfully disposed of the spoil according to the divine command, and charged them, if they knew of any transgression, that they should discover it, but Achan joined with the rest in a general protestation of innocency, and kept his countenance, like the adulterous woman that eats and wipes her mouth, and says, I have done no wickedness. Nay, 5. They have put the accursed thing among their own goods, as if they had as good a title to that as to any thing they have, never expecting to be called to an account, nor designing to make restitution. All this Joshua, though a wise and vigilant ruler, knew nothing of, till God told him, who knows all the secret wickedness that is in the world, which men know nothing of. God could at this time have told him who the person was that had done this thing, but he does not, (1.) To exercise the zeal of Joshua and Israel, in searching out the criminal. (2.) To give the sinner himself space to repent and make confession. Joshua no doubt proclaimed it immediately throughout the camp that there was such a transgression committed, upon which, if Achan had surrendered himself, and penitently owned his guilt, and prevented the scrutiny, who knows but he might have had the benefit of that law which accepted of a trespass-offering, with restitution, from those that had sinned through ignorance in the holy things of the law? Lev. v. 15, 16. But Achan never discovering himself till the lot discovered him evidenced the hardness of his heart, and therefore he found no mercy.
