And Joseph remembered the dreams which he had dreamed of them; and he said to them, "You are spies, you have come to see the weakness of the land."
They said to him, "No, my lord, but to buy food have your servants come.
We are all sons of one man, we are honest men, your servants are not spies."
He said to them, "No, it is the weakness of the land that you have come to see."
But Joseph said to them, "It is as I said to you, you are spies.
By this you shall be tested: by the life of Pharaoh, you shall not go from this place unless your youngest brother comes here.
Send one of you, and let him bring your brother, while you remain in prison, that your words may be tested, whether there is truth in you; or else, by the life of Pharaoh, surely you are spies."
And he put them all together in prison for three days.
