Joshua 7:6 KJV

4So there went up thither of the people about three thousand men: and they fled before the men of Ai.

5And the men of Ai smote of them about thirty and six men: for they chased them from before the gate even unto Shebarim, and smote them in the going down: wherefore the hearts of the people melted, and became as water.

6And Joshua rent his clothes, and fell to the earth upon his face before the ark of the LORD until the eventide, he and the elders of Israel, and put dust upon their heads.

7And Joshua said, Alas, O LORD God, wherefore hast thou at all brought this people over Jordan, to deliver us into the hand of the Amorites, to destroy us? would to God we had been content, and dwelt on the other side Jordan!

8O LORD, what shall I say, when Israel turneth their backs before their enemies!
