Charles Ellicott Commentary Joshua 7:6

"And Joshua rent his clothes, and fell to the earth upon his face before the ark of Jehovah until the evening, he and the elders of Israel; and they put dust upon their heads." — Joshua 7:6 (ASV)

Joshua rent his clothes ... —The words of Joshua and his behaviour on this occasion are consistent with all that we read of him, and confirm the notion that he was not a man of a naturally daring and adventurous spirit, but inclined to distrust his own powers; and yet utterly indomitable and unflinching in the discharge of his duty—a man of moral rather than physical courage.
