Genesis 44:30-32

30And now, when I come to thy servant my father, and the lad is not with us, — seeing that his life is bound up with his life,

31it will come to pass when he sees that the lad is not [there], that he will die; and thy servants will bring down the grey hairs of thy servant our father with sorrow to Sheol.

32For thy servant became surety for the lad to my father, saying, If I bring him not to thee, then I shall be guilty toward my father all my days.
