Joseph's brothers come to buy grain
Ten of Jacob's sons traveled to Egypt for grain and bowed before Joseph without recognizing him.
Joseph recognized his brothers, but they didn’t recognize him.
Genesis 42:8 (World English Bible)
Joseph's boyhood dream came true as his brothers bowed to the ground before him. He tested them, accusing them of spying and holding Simeon until they returned with Benjamin. Overhearing them admit their guilt over what they had done to him, Joseph turned away and wept.
