Matthew 20:20-23

20Then came to him the mother of the sons of Zebedee, with her sons, doing homage, and asking something of him.

21And he said to her, What wilt thou? She says to him, Speak [the word] that these my two sons may sit, one on thy right hand and one on thy left in thy kingdom.

22And Jesus answering said, Ye know not what ye ask. Can ye drink the cup which I am about to drink? They say to him, We are able.

23[And] he says to them, Ye shall drink indeed my cup, but to sit on my right hand and on [my] left, is not mine to give, but to those for whom it is prepared of my Father.
