Genesis 44:31

27And thy servant my father said unto us, Ye know that my wife bare me two sons:

28And the one went out from me, and I said, Surely he is torn in pieces; and I saw him not since:

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

30Now 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;

31It 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.

32For 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.

33Now 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.

34For how shall I go up to my father, and the lad be not with me? lest peradventure I see the evil that shall come on my father.
