Genesis 43:3

1And the famine was sore in the land.

2And 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.

3And Judah spake unto him, saying, The man did solemnly protest unto us, saying, Ye shall not see my face, except your brother be with you.

4If thou wilt send our brother with us, we will go down and buy thee food:

5But 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.

6And Israel said, Wherefore dealt ye so ill with me, as to tell the man whether ye had yet a brother?

7And they said, The man asked us straitly of our state, and of our kindred, saying, Is your father yet alive? have ye another brother? and we told him according to the tenor of these words: could we certainly know that he would say, Bring your brother down?
