When Jacob found out that grain was for sale in Egypt, he said to his sons, "Why do you keep looking at each other?
I've heard there's grain for sale in Egypt. Go there and buy some for us so that we won't starve to death."
Ten of Joseph's brothers went to buy grain in Egypt.
Jacob wouldn't send Joseph's brother Benjamin with the other brothers, because he was afraid that something would happen to him.
Israel's sons left with the others who were going to buy grain, because there was also famine in Canaan.
As governor of the country, Joseph was selling grain to everyone. So when Joseph's brothers arrived, they bowed in front of him with their faces touching the ground.
