If you take this one also from me, and harm or an accident happens to him, you will bring my gray hair down to Sheol in sorrow.’

when he sees that the young man is not with us, he will die; and your servants will bring the gray hair of your servant our father down to Sheol in [great] sorrow.

‘Outside the sword will bereave,And inside [the chambers] terror—For both young man and virgin,For the nursing child and the man of gray hair.

And now, here is the king walking before you. As for me, I am old and gray, and here are my sons with you. I have walked before you from my childhood to this day.

The glory of young men is their [physical] strength,And the honor of aged men is their gray head [representing wisdom and experience].

Strangers have devoured his strength,Yet he does not know it;Gray hairs are sprinkled on him,Yet he does not know.
