Genesis

Then he commanded [the one] who [was] over his household, saying, "Fill the sacks of the men [with] food as much as they are able to carry, and put each one's money in the mouth of his sack.

And my cup--the cup of silver--you shall put into the mouth of the sack of the youngest, and the money for his grain. And he did according to the word of Joseph that he had commanded.
