'Gray' in the Bible

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 if ye take this one also from me, and harm befall him, ye will bring down my gray hairs with sorrow to Sheol.

it will come to pass, when he seeth that the lad is not with us , that he will die: and thy servants will bring down the gray hairs of thy servant our father with sorrow to Sheol.

Without shall the sword bereave, And in the chambers terror; It shall destroy both young man and virgin, The suckling with the man of gray hairs.

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