Genesis 44:29

And he commanded the steward of his house, saying, Fill the men's sacks with food, as much as they can carry, and put every man's money in his sack's mouth.

And put my cup, the silver cup, in the sack's mouth of the youngest, and his corn money. And he did according to the word that Joseph had spoken.

As soon as the morning was light, the men were sent away, they and their asses.

And when they were gone out of the city, and not yet far off, Joseph said unto his steward, Up, follow after the men; and when thou dost overtake them, say unto them, Wherefore have ye rewarded evil for good?
