KJV(i)
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.
