Genesis 42:5-13

So Israel’s sons were among those who went to buy grain, for there was famine in the land of Canaan also. Now 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. As 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.” Although Joseph recognized his brothers, they did not recognize him. Then he remembered his dreams about them and said to them, “You are spies! You have come to see where our land is unprotected.” “No, my lord,” they answered. “Your servants have come to buy food. We are all the sons of one man. Your servants are honest men, not spies.” “No!” he said to them. “You have come to see where our land is unprotected.” But they replied, “Your servants were twelve brothers, the sons of one man, who lives in the land of Canaan. The youngest is now with our father, and one is no more.”
