'Written' in the Bible

As it is written in Isaiah the prophet:“Behold, I send My messenger ahead of You,Who will prepare Your way;

And He said to them, “Rightly did Isaiah prophesy of you hypocrites, as it is written:‘This people honors Me with their lips,But their heart is far away from Me.

And He said to them, “Elijah does first come and restore all things. And yet how is it written of the Son of Man that He will suffer many things and be treated with contempt?

But I say to you that Elijah has indeed come, and they did to him whatever they wished, just as it is written of him.”

And He began to teach and say to them, “Is it not written, ‘My house shall be called a house of prayer for all the nations’? But you have made it a robbers’ den.”

For the Son of Man is to go just as it is written of Him; but woe to that man by whom the Son of Man is betrayed! It would have been good for that man if he had not been born.”

And Jesus *said to them, “You will all fall away, because it is written, ‘I will strike down the shepherd, and the sheep shall be scattered.’
