Genesis 42:38 - Inconsolable Sorrow

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.

then shall ye bring down my gray hairs with sorrow to the grave: Returning home without Benjamin would break Jacob's tender heart. He would become as one dead (Genesis 44:31); living out the rest of his days without a remedy to rekindle his zeal for life, mourning for his sons until the day he dies (Genesis 37:35).
