'Add' in the Bible

And he saith, 'What is the word which He hath spoken unto thee? I pray thee, hide it not from me; so doth God do to thee, and so doth He add, if thou hidest from me a word of all the words that He hath spoken unto thee.'

And Saul saith, 'Thus doth God do, and thus doth He add, for thou dost certainly die, Jonathan.'

thus doth Jehovah do to Jonathan, and thus doth He add; when the evil concerning thee is good to my father, then I have uncovered thine ear, and sent thee away, and thou hast gone in peace, and Jehovah is with thee, as he was with my father;

thus doth God do to the enemies of David, and thus He doth add, if I leave of all that he hath till the light of the morning -- of those sitting on the wall.'
