'Cup' in the Bible

And he said to me, What do you see? And I said, I see a light-support, made all of gold, with its cup on the top of it and seven lights on it; and there are seven pipes to every one of the lights which are on the top of it;

And two olive-trees by it, one on the right side of the cup and one on the left.

Behold, I will make Jerusalem a cup of trembling unto all the people round about, when they shall be in the siege both against Judah and against Jerusalem.
