Joshua 7:6

And Joshua rent his clothes, as a sign of the deepest distress and mourning, and fell to the earth upon his face before the ark of the Lord until the eventide, in a silent and yet eloquent appeal to the Lord, he and the elders of Israel, and put dust upon their heads, another custom betokening the deepest mourning, 1 Samuel 4:12; 2 Samuel 1:2; 2 Samuel 13:19.
