Genesis 43:19-22

So they went up to Joseph's chief servant at the door of the house, And said, O my lord, we only came down the first time to get food; And when we came to our night's resting-place, on opening our bags we saw that every man's money was in the mouth of his bag, all our money in full weight: and we have it with us to give it back; As well as more money, with which to get food: we have no idea who put our money in our bags.
