Genesis 43:12, 15, 21

Also take double the money that was put back in your sacks, as it was probably someone’s mistake.

So the men packed Jacob’s gifts and double the money and headed off with Benjamin. They finally arrived in Egypt and presented themselves to Joseph.

But as we were returning home, we stopped for the night and opened our sacks. Then we discovered that each man’s money—the exact amount paid—was in the top of his sack! Here it is; we have brought it back with us.
