Later on, one of them opened up his sack to give his donkey some fodder after they had stopped at the place where they intended to lodge for the night. There, in the mouth of his sack, was all of his money!

Also take twice as much money with you so you can return the money that had been replaced in the mouth of your sacks. Maybe it was an accounting mistake on his part.

when we arrived at our overnight lodging place, we opened our sacks and discovered each man's money was still in the mouth of his sack. All of our money was there! We've brought it back with us in full.
