Genesis 42:1-6

When Jacob learned there was food in Egypt, he said to his sons, “Why are you standing around here staring at each other? I hear there is grain in Egypt; go there and buy some for us so we don’t all starve to death.” So Joseph’s ten half brothers went down to buy grain in Egypt, but Jacob did not send Joseph’s full brother Benjamin with them, because he feared something might happen to him. So Israel’s sons were among those who went to Egypt to buy grain, for the famine in the land of Canaan was severe. Now Joseph was the governor of the land of Egypt, which meant he supervised the sale of grain to all the people. One day, Joseph’s ten brothers came and bowed down before him with their faces on the ground.
