Thematic Bible: Its completion by zerubbabel foretold, to encourage the jews

So I asked the angel who talked with me, What are these, my lord? Then the angel who talked with me answered me, Do you not know what these are? And I said, No, my lord. Then he said to me, This [addition of the bowl to the candlestick, causing it to yield a ceaseless supply of oil from the olive trees] is the word of the Lord to Zerubbabel, saying, Not by might, nor by power, but by My Spirit [of Whom the oil is a symbol], says the Lord of hosts. read more.
For who are you, O great mountain [of human obstacles]? Before Zerubbabel [who with Joshua had led the return of the exiles from Babylon and was undertaking the rebuilding of the temple, before him] you shall become a plain [a mere molehill]! And he shall bring forth the finishing gable stone [of the new temple] with loud shoutings of the people, crying, Grace, grace to it! Moreover, the word of the Lord came to me, saying, The hands of Zerubbabel have laid the foundations of this house; his hands shall also finish it. Then you shall know (recognize and understand) that the Lord of hosts has sent me [His messenger] to you. Who [with reason] despises the day of small things? For these seven shall rejoice when they see the plummet in the hand of Zerubbabel. [These seven] are the eyes of the Lord which run to and fro throughout the whole earth.
