Genesis 43:10 (KJV)

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.

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

And 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?

And Judah said unto Israel his father, Send the lad with me, and we will arise and go; that we may live, and not die, both we, and thou, and also our little ones.

I will be surety for him; of my hand shalt thou require him: if I bring him not unto thee, and set him before thee, then let me bear the blame for ever:

And their father Israel said unto them, If it must be so now, do this; take of the best fruits in the land in your vessels, and carry down the man a present, a little balm, and a little honey, spices, and myrrh, nuts, and almonds:

And take double money in your hand; and the money that was brought again in the mouth of your sacks, carry it again in your hand; peradventure it was an oversight:

Take also your brother, and arise, go again unto the man:

And God Almighty give you mercy before the man, that he may send away your other brother, and Benjamin. If I be bereaved of my children, I am bereaved.

And the men took that present, and they took double money in their hand and Benjamin; and rose up, and went down to Egypt, and stood before Joseph.
