Genesis 44:30-32

30“Now if I come to your servant my father and the boy isn’t with us, since his life is bound to his life,

31when he sees that the boy is no more, he’ll die. Then your servants will bring the grey hair of your servant our father down to Sheol in grief.

32For your servant became pledge for the boy with my father saying, ‘If I don’t bring him back to you, I will bear the blame before my father all my days.’
