Genesis 42:1-2, 6-7

When Jacob heard that grain was available in Egypt, he said to his sons, “Why are you standing around looking at one another? I have heard there is grain in Egypt. Go down there, and buy enough grain to keep us alive. Otherwise we’ll die.”

Since Joseph was governor of all Egypt and in charge of selling grain to all the people, it was to him that his brothers came. When they arrived, they bowed before him with their faces to the ground. Joseph recognized his brothers instantly, but he pretended to be a stranger and spoke harshly to them. “Where are you from?” he demanded. “From the land of Canaan,” they replied. “We have come to buy food.”
