Genesis 42:6-9

6Now Joseph was the governor of the land, the person who sold grain to all its people. So when Joseph’s brothers arrived, they bowed down to him with their faces to the ground.

7As soon as Joseph saw his brothers, he recognized them, but he pretended to be a stranger and spoke harshly to them. “Where do you come from?” he asked. “From the land of Canaan,” they replied, “to buy food.”

8Although Joseph recognized his brothers, they did not recognize him.

9Then he remembered his dreams about them and said to them, “You are spies! You have come to see where our land is unprotected.”
