'It is Written' in the Bible

As it is written in Isaiah the prophet, "Look, I am sending my messenger ahead of you, who will prepare your way,

He said to them, "Isaiah prophesied correctly about you hypocrites, as it is written: 'This people honors me with their lips, but their heart is far from me.

But I tell you that Elijah has certainly come, and they did to him whatever they wanted, just as it is written about him."

For the Son of Man will go as it is written about him, but woe to that man by whom the Son of Man is betrayed! It would be better for him if he had never been born."

Then Jesus said to them, "You will all fall away, for it is written, 'I will strike the shepherd, and the sheep will be scattered.'
