'It is Written' in the Bible

As it is written in the prophet Isaiah, Here I send my messenger before your face to prepare the way for you:

He said to them, "Isaiah made a grand prophecy about you hypocrites ??as it is written, This people honours me with their lips, but their heart is far away from me:

As for Elijah, I tell you he has come already, and they have done to him whatever they pleased ??as it is written of him."

Jesus said to them, "You will all be disconcerted, for it is written: I will strike at the shepherd, and, the sheep will be scattered.
