Revised Standard Version

Then every man quickly lowered his sack to the ground, and every man opened his sack.

See the chapter Copy

And as one of them opened his sack to give his ass provender at the lodging place, he saw his money in the mouth of his sack;

He said, “Let it be as you say: he with whom it is found shall be my slave, and the rest of you shall be blameless.”

And he searched, beginning with the eldest and ending with the youngest; and the cup was found in Benjamin's sack.
