Genesis 44 · a question people ask
Why did Joseph set this trap?
This chapter doesn't say. Earlier Joseph told the brothers he would test them, "that your words may be tested, whether there is truth in you" (42:16). Here he gives them a way home without Benjamin: "go up in peace to your father" (44:17). Judah offers himself instead (44:33), and when Judah has finished, "Joseph couldn’t control himself" (45:1).
The verses
“Send one of you, and let him get your brother, and you shall be bound, that your words may be tested, whether there is truth in you, or else by the life of Pharaoh surely you are spies.””
“He said, “Far be it from me that I should do so. The man in whose hand the cup is found, he will be my slave; but as for you, go up in peace to your father.””
“Now therefore, please let your servant stay instead of the boy, my lord’s slave; and let the boy go up with his brothers.”
“Then Joseph couldn’t control himself before all those who stood before him, and he called out, “Cause everyone to go out from me!” No one else stood with him, while Joseph made himself known to his brothers.”
