Verse 13. - Sanctify the people. See note on Joshua 3:5. Thou canst not stand before thine enemies. Observe the singular number here, intensifying the testimony of the whole history to the fact that Israel was one body before the Lord. And observe, moreover, how the existence of secret sin, even though unknown to and undetected by him in whom it lurks, has power to enfeeble the soul in its conflict with its enemies. Hence we learn the duties Of watchfulness and careful examination of the soul by the light of God's Word.

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.Up, sanctify the people,.... The word "up" not only signifies getting up from the ground on which he lay, but to bestir himself, and to be active in what he would now be enjoined and directed to do, and in the first place to "sanctify the people", that is, by giving them orders to do it themselves:

and say, sanctify yourselves against tomorrow; either by some ceremonial ablutions, or by the performance of moral duties, as prayer, repentance, and good works; or rather, they were to "prepare" themselves, as the Targum and Kimchi interpret it, to get ready against the morrow, and expect to be thoroughly searched, in order to find out the person who had taken the accursed thing:

for thus saith the Lord God of Israel, there is an accursed thing in the midst of thee, O Israel; an accursed person, who had taken of what was devoted to the Lord for his own use, and so accursed:

thou canst not stand before thine enemies, until ye take away the accursed thing from among you; by putting him to death.
