Jamieson, Fausset and Brown on Joshua 7:6-9

6-9. Joshua rent his clothes, and fell to the earth ... before the ark ... he and the elders--It is evident, from those tokens of humiliation and sorrow, that a solemn fast was observed on this occasion. The language of Joshua's prayer is thought by many to savor of human infirmity and to be wanting in that reverence and submission he owed to God. But, although apparently breathing a spirit of bold remonstrance and complaint, it was in reality the effusion of a deeply humbled and afflicted mind, expressing his belief that God could not, after having so miraculously brought His people over Jordan into the promised land, intend to destroy them, to expose them to the insults of their triumphant enemies, and bring reproach upon His own name for inconstancy or unkindness to His people, or inability to resist their enemies. Unable to understand the cause of the present calamity, he owned the hand of God.
