'Cup' in the Bible

And whoever gives you a cup of water to drink because of My name, since you belong to the Messiah—I assure you: He will never lose his reward.

But Jesus said to them, “You don’t know what you’re asking. Are you able to drink the cup I drink or to be baptized with the baptism I am baptized with?”

“We are able,” they told Him.Jesus said to them, “You will drink the cup I drink, and you will be baptized with the baptism I am baptized with.

Then He took a cup, and after giving thanks, He gave it to them, and so they all drank from it.

And He said, “Abba, Father! All things are possible for You. Take this cup away from Me. Nevertheless, not what I will, but what You will.”
