Mark 10:37

34 and they shall mock him, and shall spit upon him, and shall scourge him, and shall kill him; and after three days he shall rise again.

35 And there come near unto him James and John, the sons of Zebedee, saying unto him, Teacher, we would that thou shouldest do for us whatsoever we shall ask of thee.

36 And he said unto them, What would ye that I should do for you?

37 And they said unto him, Grant unto us that we may sit, one on thy right hand, and one on [thy] left hand, in thy glory.

38 But Jesus said unto them, Ye know not what ye ask. Are ye able to drink the cup that I drink? or to be baptized with the baptism that I am baptized with?

39 And they said unto him, We are able. And Jesus said unto them, The cup that I drink ye shall drink; and with the baptism that I am baptized withal shall ye be baptized:

40 but to sit on my right hand or on [my] left hand is not mine to give; but [it is for them] for whom it hath been prepared.
