Matthew 20:21-23

And he said unto her, What wouldest thou? She saith unto him, Command that these my two sons may sit, one on thy right hand, and one on thy left hand, in thy kingdom. But Jesus answered and said, Ye know not what ye ask. Are ye able to drink the cup that I am about to drink? They say unto him, We are able. He saith unto them, My cup indeed ye shall drink: but to sit on my right hand, and on my left hand, is not mine to give; but it is for them for whom it hath been prepared of my Father.
