Zechariah 2:2-5

Then I said, “Where are you going?” And he said to me, “To measure Jerusalem, to see what is its width and what is its length.” And behold, the angel who talked with me came forward, and another angel came forward to meet him and said to him, “Run, say to that young man, ‘Jerusalem shall be inhabited as villages without walls, because of the multitude of people and livestock in it. And I will be to her a wall of fire all around, declares the LORD, and I will be the glory in her midst.’”
