'Cup of' in the Bible

Now, the cup of Pharaoh, being in my hand, I took the ripe grapes and pressed them out into the cup of Pharaoh, and set the cup upon Pharaohs palm.

In three days more, will Pharaoh lift up thy head, and restore thee to thine office, and thou shalt set the cup of Pharaoh in his hand, according to the former custom when thou wast his butler.

and my cup - the cup of silver, shalt thou put in the mouth of the sack of the youngest, with his corn-silver. So he did, according to the word of Joseph, which he had spoken.
