'Cup' in the Bible

For whosoever shall give you a cup of water to drink in my name, because ye belong to Christ, verily I say unto you, he shall not lose his reward.

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:

Jesus told them, "You will drink from the cup that I'm going to drink and be baptized with the baptism with which I'm going to be baptized. But it's not up to me to grant you a seat at my right or my left. Those positions have already been prepared for others."

And he took the cup, and when he had given thanks, he gave it to them: and they all drank of it.

And he said, Abba, Father, all things are possible unto thee; take away this cup from me: nevertheless not what I will, but what thou wilt.
