Genesis 43:3

And the famine was sore in the land.

And it came to pass, when they had eaten up the corn which they had brought out of Egypt, their father said unto them, Go again, buy us a little food.

If thou wilt send our brother with us, we will go down and buy thee food:

But if thou wilt not send him, we will not go down: for the man said unto us, Ye shall not see my face, except your brother be with you.
