'Hoar' in the Bible

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

Now therefore hold him not guiltless: for thou art a wise man, and knowest what thou oughtest to do unto him; but his hoar head bring thou down to the grave with blood.

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