'Gray' in the Bible

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

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.

The sword without, and terror within, shall destroy both the young man and the virgin, the suckling also with the man of gray hairs.

The glory of young men is their strength: and the beauty of old men is the gray head.

Strangers have devoured his strength, and he knoweth it not: yea, gray hairs are here and there upon him, yet he knoweth not.
