'Lights' in the Bible

So I said, "I have been watching and look! there is a menorah made completely of gold with a bowl on top of it. And there are seven lights on it, along with seven feeder channels to the lamps, which are also on top of it. Two olive trees are near it, one on the right side of the bowl and one on the left."

For who has despised the time of insignificant things? They will rejoice to see the plumb line in the hand of Zerubbabel. These seven lights represent the eyes of the LORD, which are looking throughout all of the earth."

I also asked him a second question: "What are these two olive branches on either side of the two golden feeder channels that carry the golden oil to the seven lights?"
