'Add' in the Bible

and Jehovah saith unto me, 'What art thou seeing, Amos?' And I say, 'A plumb-line;' and the Lord saith: 'Lo, I am setting a plumb-line in the midst of My people Israel, I do not add any more to pass over to it.

and at Beth-El do not add to prophesy any more, for it is the king's sanctuary, and it is the royal house.'

And He saith, 'What art thou seeing, Amos?' and I say, 'A basket of summer-fruit.' And Jehovah saith unto me: 'The end hath come unto My people Israel, I do not add any more to pass over to it.
