'As It is Written' in the Bible

Even as it is written in Isaiah the prophet, Behold, I send my messenger before thy face, Who shall prepare thy way.

And he said unto them, Well did Isaiah prophesy of you hypocrites, as it is written, This people honoreth me with their lips, But their heart is far from me.

But I say unto you, that Elijah is come, and they have also done unto him whatsoever they would, even as it is written of him.

For the Son of man goeth, even as it is written of him: but woe unto that man through whom the Son of man is betrayed! good were it for that man if he had not been born.
