The Book of Zechariah, in the Old Testament of the Bible, takes its name from a priest who returned to Jerusalem with exiles from Babylon.
Zech. 6:15.... Those who are far off shall come and help to build the temple of the Lord; and you shall know that the Lord of hosts has sent me to you. This will happen if you diligently obey the voice of the Lord your God.
Zech. 8:3......Thus says the Lord: I will return to Zion, and will dwell in the midst of Jerusalem; Jerusalem shall be called the faithful city, and the mountain of the Lord of hosts shall be called the holy mountain.
