Joshua 9:12-13

“ This our bread we took hot for our provision out of our houses on the day we came out to go to you, but now, behold, it is dry, and has become mouldy. And these wineskins, which we filled, were new, and look they are torn, and these our clothes, and our shoes, have become old by reason of the very long journey.”

They then presented their masterstroke, the condition of their bread, wine and clothing. They pointed out how old it was and how long they must have been on their journey for it to become so. Worn out shoes, clothes showing signs of wear, mouldy food, torn wineskins. What more proof did they need?
