Genesis 42:5

3Joseph’s ten brothers went down to buy grain from Egypt.

4But Jacob didn’t send Benjamin, Joseph’s brother, with his brothers; for he said, “Lest perhaps harm happen to him.”

5The sons of Israel came to buy among those who came, for the famine was in the land of Canaan.

6Joseph was the governor over the land. It was he who sold to all the people of the land. Joseph’s brothers came, and bowed themselves down to him with their faces to the earth.

7Joseph saw his brothers, and he recognized them, but acted like a stranger to them, and spoke roughly with them. He said to them, “Where did you come from?” They said, “From the land of Canaan, to buy food.”
