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 14

14:4 And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
