Zechariah 4:3 Meaning

1And the angel that talked with me came again, and waked me, as a man that is wakened out of his sleep,

2And said unto me, What seest thou? And I said, I have looked, and behold a candlestick all of gold, with a bowl upon the top of it, and his seven lamps thereon, and seven pipes to the seven lamps, which are upon the top thereof:

3And two olive trees by it, one upon the right side of the bowl, and the other upon the left side thereof.

4So I answered and spake to the angel that talked with me, saying, What are these, my lord?

5Then the angel that talked with me answered and said unto me, Knowest thou not what these be? And I said, No, my lord.
