Genesis 44:30-32

30"Now therefore, as soon as I come to your servant my father, and the boy is not with us, then, as his life is bound up in the boy's life,

31as soon as he sees that the boy is not with us, he will die, and your servants will bring down the gray hairs of your servant our father with sorrow to Sheol.

32For your servant became a pledge of safety for the boy to my father, saying, 'If I do not bring him back to you, then I shall bear the blame before my father all my life.'
