Genesis 42:1-5

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.
