Genesis 42:6-9

6Since Joseph was governor of all Egypt and in charge of selling grain to all the people, it was to him that his brothers came. When they arrived, they bowed before him with their faces to the ground.

7Joseph recognized his brothers instantly, but he pretended to be a stranger and spoke harshly to them. “Where are you from?” he demanded. “From the land of Canaan,” they replied. “We have come to buy food.”

8Although Joseph recognized his brothers, they didn’t recognize him.

9And he remembered the dreams he’d had about them many years before. He said to them, “You are spies! You have come to see how vulnerable our land has become.”
