Genesis 42:14-16

Revised Standard Version

¹⁴ But Joseph said to them, “It is as I said to you, you are spies. ¹⁵ By this you shall be tested: by the life of Pharaoh, you shall not go from this place unless your youngest brother comes here. ¹⁶ 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.”
