Mark 10:38-40

38But Yeshua answered them, “You don’t know what you’re asking! Are you able to drink the cup I drink, or endure the immersion I must endure?”

39They said to Him, “We are able.” And Yeshua said to them, “You will drink the cup I drink, and you will endure the immersion I must endure.

40But to sit on My right or left is not Mine to grant—it is for those for whom it has been prepared.”
