Send one of you, and let him fetch your brother, and you shall be kept in prison, that your words may be proved, whether there be any truth in you: or else by the life of Pharaoh surely you are spies.

And Joseph saw his brothers, and he knew them, but made himself strange to them, and spoke roughly to them; and he said to them, From where come you? And they said, From the land of Canaan to buy food.
How shall I pardon you for this? your children have forsaken me, and sworn by them that are no gods: when I had fed them to the full, they then committed adultery, and assembled themselves by troops in the harlots' houses.
