Genesis 43:16-18

And when Joseph saw Benjamin with them, he said to the ruler of his house, Bring these men home, and slay, and make ready; for these men shall dine with me at noon. And the man did as Joseph bade; and the man brought the men into Joseph's house. And the men were afraid, because they were brought into Joseph's house; and they said, Because of the money that was returned in our sacks at the first time are we brought in; that he may seek occasion against us, and fall upon us, and take us for bondmen, and our asses.
