Zechariah 2:4-5

4and he said to the second angel, “Run, speak to that young man, saying, ‘Jerusalem will be inhabited [like villages] without walls [spreading out into the open country] because of the great number of people and livestock in it.

5For I,’ declares the Lord, ‘will be a wall of fire around her [protecting her from enemies], and I will be the glory in her midst.’ ”
