Genesis 42:1-9

Now when Jacob (Israel) learned that there was grain in Egypt, he said to his sons, “Why are you staring at one another [in bewilderment and not taking action]?” He said, “I have heard that there is grain in Egypt; go down there and buy [some] grain for us, so that we may live and not die [of starvation].” So ten of Joseph’s brothers went down to buy grain in Egypt. But Jacob did not send Benjamin, Joseph’s [younger] brother, with his brothers, for he said, “I am afraid that some harm or injury may come to him.” So the sons of Israel came [to Egypt] to buy grain along with the others who were coming, for famine was in the land of Canaan also. Now Joseph was the ruler over the land, and he was the one who sold [grain] to all the people of the land; and Joseph’s [half] brothers came and bowed down before him with their faces to the ground. When Joseph saw his brothers he recognized them, but [hiding his identity] he treated them as strangers and spoke harshly to them. He said to them, “Where have you come from?” And they said, “From the land of Canaan, to buy food.” Joseph recognized his brothers, but they did not recognize him. Joseph remembered the dreams he had dreamed about them, and said to them, “You are spies; you have come [with a malicious purpose] to observe the undefended parts of our land.”
