'Whether' in the Bible

And he said, While the child was yet alive, I fasted and wept: for I said, Who knoweth whether Jehovah will not be gracious to me, that the child may live?

And Ittai answered the king, and said, As Jehovah liveth, and as my lord the king liveth, surely in what place my lord the king shall be, whether for death or for life, even there also will thy servant be.
