Zechariah is a book of prophecies of a contemporary of Haggai. Zechariah urges the people to rebuild the Temple for he too believes in the imminent coming of the messianic kingdom. Both Zechariah and Haggai are concerned with the messianic hope and establishing Judah’s role in the fulfillment of that glorious hope.

Zechariah 4

4:9 The hands of Zerubbabel have laid the foundation of this house; his hands shall also finish it; and thou shalt know that the LORD of hosts hath sent me unto you.
