'Hoar' in the Bible

Do therefore according to thy wisdom, and let not his hoar head go down to Sheol in peace.

Now therefore hold him not guiltless, for thou art a wise man; and thou wilt know what thou oughtest to do unto him, and thou shalt bring his hoar head down to Sheol with blood.

and even to old age I am he, and even to hoar hairs will I carry you ; I have made, and I will bear; yea, I will carry, and will deliver.
