7:1-5 Achan took some of the spoil of Jericho. The love of the world is that root of bitterness, which of all others is most hardly rooted up. We should take heed of sin ourselves, lest by it many be defiled or disquieted, Heb 12:15; and take heed of having fellowship with sinners, lest we share their guilt. It concerns us to watch over one another to prevent sin, because others' sins may be to our damage. The easy conquest of Jericho excited contempt of the enemy, and a disposition to expect the Lord to do all for them without their using proper means. Thus men abuse the doctrines of Divine grace, and the promises of God, into excuses for their own sloth and self-indulgence. We are to work out our own salvation, though it is God that works in us. It was a dear victory to the Canaanites, whereby Israel was awakened and reformed, and reconciled to their God, and the people of Canaan hardened to their own ruin.

7:6-9 Joshua's concern for the honour of God, more than even for the fate of Israel, was the language of the Spirit of adoption. He pleaded with God. He laments their defeat, as he feared it would reflect on God's wisdom and power, his goodness and faithfulness. We cannot at any time urge a better plea than this, Lord, what wilt thou do for thy great name? Let God be glorified in all, and then welcome his whole will.

7:10-15 God awakens Joshua to inquiry, by telling him that when this accursed thing was put away, all would be well. Times of danger and trouble should be times of reformation. We should look at home, into our own hearts, into our own houses, and make diligent search to find out if there be not some accursed thing there, which God sees and abhors; some secret lust, some unlawful gain, some undue withholding from God or from others. We cannot prosper, until the accursed thing be destroyed out of our hearts, and put out of our habitations and our families, and forsaken in our lives. When the sin of sinners finds them out, God is to be acknowledged. With a certain and unerring judgment, the righteous God does and will distinguish between the innocent and the guilty; so that though the righteous are of the same tribe, and family, and household with the wicked, yet they never shall be treated as the wicked.

7:16-26 See the folly of those that promise themselves secrecy in sin. The righteous God has many ways of bringing to light the hidden works of darkness. See also, how much it is our concern, when God is contending with us, to find out the cause that troubles us. We must pray with holy Job, Lord, show me wherefore thou contendest with me. Achan's sin began in the eye. He saw these fine things, as Eve saw the forbidden fruit. See what comes of suffering the heart to walk after the eyes, and what need we have to make this covenant with our eyes, that if they wander they shall be sure to weep for it. It proceeded out of the heart. They that would be kept from sinful actions, must mortify and check in themselves sinful desires, particularly the desire of worldly wealth. Had Achan looked upon these things with an eye of faith, he would have seen they were accursed things, and would have dreaded them; but looking on them with an eye of sense only, he saw them as goodly things, and coveted them. When he had committed the sin, he tried to hide it. As soon as he had got this plunder, it became his burden, and he dared not to use his ill-gotten treasure. So differently do objects of temptation appear at a distance, to what they do when they have been gotten. See the deceitfulness of sin; that which is pleasing in the commission, is bitter in the reflection. See how they will be deceived that rob God. Sin is a very troublesome thing, not only to a sinner himself, but to all about him. The righteous God will certainly recompense tribulation to them that trouble his people. Achan perished not alone in his sin. They lose their own, who grasp at more than their own. His sons and daughters were put to death with him. It is probable that they helped to hide the things; they must have known of them. What fatal consequences follow, even in this world, to the sinner himself, and to all belonging him! One sinner destroys much good. What, then, will be the wrath to come? Let us flee from it to Christ Jesus as the sinner's Friend. There are circumstances in the confession of Achan, marking the progress of sin, from its first entrance into the heart to its being done, which may serve as the history of almost every offence against the law of God, and the sacrifice of Jesus Christ.
