Joshua sent men from Jericho to Ai, which is beside Beth Aven, on the east side of Bethel, and spoke to them, saying, Go up and spy out the land. The men went up and spied out Ai.
      I. Achan sinning, Joshua 7:1; Joshua 7:1. Here is only a general mention made of the sin; we shall afterwards have a more particular account of it from his own mouth. The sin is here said to be taking of the accursed thing, in disobedience to the command and in defiance of the threatening, Joshua 6:18; Joshua 6:18. In the sacking of Jericho orders were given that they should neither spare any lives nor take any treasure to themselves; we read not of the breach of the former prohibition (there were none to whom they showed any mercy), but of the latter: compassion was put off and yielded to the law, but covetousness was indulged. The love of the world is that root of bitterness which of all others is most hardly rooted up. Yet the history of Achan is a plain intimation that he of all the thousands of Israel was the only delinquent in this matter. Had there been more in like manner guilty, no doubt we should have heard of it: and it is strange there were no more. The temptation was strong. It was easy to suggest what a pity it was that so many things of value should be burnt; to what purpose is this waste? In plundering cities, every man reckons himself entitled to what he can lay his hands on. It was easy to promise themselves secrecy and impunity. Yet by the grace of God such impressions were made upon the minds of the Israelites by the ordinances of God, circumcision and the passover, which they had lately been partakers of, and by the providences of God which had been concerning them, that they stood in awe of the divine precept and judgment, and generously denied themselves in obedience to their God. And yet, though it was a single person that sinned, the children of Israel are said to commit the trespass, because one of their body did it, and he was not as yet separated from them, nor disowned by them. They did it, that is, by what Achan did guilt was brought upon the whole society of which he was a member. This should be a warning to us to take heed of sin ourselves, lest by it many be defiled or disquieted (Hebrews 12:15), and to take heed of having fellowship with sinners, and of being in league with them, lest we share in their guilt. Many a careful tradesman has been broken by a careless partner. And it concerns us to watch over one another for the preventing of sin, because others' sins may redound to our damage.
