And he said unto them, What would ye that I should do for you?
They said unto him, Grant unto us that we may sit, one on thy right hand, and the other on thy left hand, in thy glory.
But Jesus said unto them, Ye know not what ye ask: can ye drink of the cup that I drink of? and be baptized with the baptism that I am baptized with?
And they said unto him, We can. And Jesus said unto them, Ye shall indeed drink of the cup that I drink of; and with the baptism that I am baptized withal shall ye be baptized:
