Genesis 43:21-22

21and when we arrived at the inn [after leaving here], we opened our sacks and there was each man’s money [with which he had paid for grain], in full, returned in the mouth of his sack. So we have brought it back [this time].

22We have also brought down with us additional money to buy food; we do not know who put our money [back] in our sacks [last time].”
