Matthew Chapter 20 Young's Literal Translation
And Jesus answering said, `Ye have not known what ye ask for yourselves; are ye able to drink of the cup that I am about to drink? and with the baptism that I am baptized with, to be baptized?' They say to him, `We are able.'
And he saith to them, `Of my cup indeed ye shall drink, and with the baptism that I am baptized with ye shall be baptized; but to sit on my right hand and on my left is not mine to give, but -- to those for whom it hath been prepared by my father.'
