Genesis 43:8 (KJV)

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:

For except we had lingered, surely now we had returned this second time.
