What does Genesis 42:38 mean?

And he said, My son shall not go down with you; for his brother is dead, and he only is left: if harm befall him by the way in which ye go, then will ye bring down my gray hairs with sorrow to Sheol.

And he said, My son shall not go down with you; for his brother is dead, and he is left alone: if mischief befall him by the way in the which ye go, then shall ye bring down my gray hairs with sorrow to the grave.

And he said, My son shall not go down with you; for his brother is dead, and he only is left: if harm befall him by the way in which ye go, then will ye bring down my gray hairs with sorrow to Sheol.

And he said, I will not let my son go down with you; for his brother is dead and he is all I have: if evil overtakes him on the journey, then through you will my grey head go down to the underworld in sorrow.

and he saith, `My son doth not go down with you, for his brother <FI>is<Fi> dead, and he by himself is left; when mischief hath met him in the way in which ye go, then ye have brought down my grey hairs in sorrow to sheol.'

But he said: My son shall not go down with you: his brother is dead, and he is left alone: if any mischief befall him in the land to which you go, you will bring down my grey hairs with sorrow to hell.

But he said, My son shall not go down with you, for his brother is dead, and he alone is left; and if mischief should befall him by the way in which ye go, then would ye bring down my grey hairs with sorrow to Sheol.
