Genesis 44:3 (KJV)

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.

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?

Is not this it in which my lord drinketh, and whereby indeed he divineth? ye have done evil in so doing.

And he overtook them, and he spake unto them these same words.

And they said unto him, Wherefore saith my lord these words? God forbid that thy servants should do according to this thing:

Behold, the money, which we found in our sacks' mouths, we brought again unto thee out of the land of Canaan: how then should we steal out of thy lord's house silver or gold?
