'Cup' in the Bible

For whoever gives you a cup of water to drink in [my] name because you are Christ's, truly I say to you that he will never lose his reward.

But Jesus said to them, "You do not know what you are asking! Are you able to drink the cup that I drink, or to be baptized with the baptism that I am baptized with?"

And they said to him, "We are able." So Jesus said to them, "You will drink the cup that I drink, and you will be baptized with the baptism that I am baptized with,

And [after] taking the cup [and] giving thanks, he gave [it] to them, and they all drank from it.

And he said, "Abba, Father, all [things] [are] possible for you! Take away this cup from me! Yet not what I will, but what you [will]."
