Genesis 42:6-7

Now Joseph was the ruler over the land; he was the one who sold to all the people of the land. And Joseph’s brothers came and bowed down to him with their faces to the ground. When Joseph saw his brothers he recognized them, but he disguised himself to them and spoke to them harshly. And he said to them, “Where have you come from?” And they said, “From the land of Canaan, to buy food.”
