Genesis 42:3

Now when Jacob saw that there was corn in Egypt, Jacob said unto his sons, Why do ye look one upon another?

And he said, Behold, I have heard that there is corn in Egypt: get you down thither, and buy for us from thence; that we may live, and not die.

But Benjamin, Joseph's brother, Jacob sent not with his brethren; for he said, Lest peradventure mischief befall him.

And the sons of Israel came to buy corn among those that came: for the famine was in the land of Canaan.
