“Sing and rejoice, O daughter of Zion, for behold, I come and I will dwell [tabernacle] in your midst, declares the Lord. And many nations shall join themselves to the Lord in that day, and shall be my people. And I will dwell in your midst, and you shall know that the Lord of hosts has sent me to you.”
~Zechariah 2:10-11
