Genesis 44:31

²⁹  And if ye take this also from me, and mischief befall him, ye shall bring down my gray hairs with sorrow to the grave.

³⁰  Now therefore when I come to thy servant my father, and the lad be not with us; seeing that his life is bound up in the lad's life;

³¹  It shall come to pass, when he seeth that the lad is not with us, that he will die: and thy servants shall bring down the gray hairs of thy servant our father with sorrow to the grave.

³²  For thy servant became surety for the lad unto my father, saying, If I bring him not unto thee, then I shall bear the blame to my father for ever.

³³  Now therefore, I pray thee, let thy servant abide instead of the lad a bondman to my lord; and let the lad go up with his brethren.
