Genesis 42:5-7

Thus the sons of Israel came to buy among the others who came, for the famine was in the land of Canaan. Now Joseph was governor over the land. He was the one who sold to all the people of the land. And Joseph’s brothers came and bowed themselves before him with their faces to the ground. Joseph saw his brothers and recognized them, but he treated them like strangers and spoke roughly to them. “Where do you come from?” he said. They said, “From the land of Canaan, to buy food.”
