Zechariah 2:2-5

“Where are you going?” I asked. He replied, “I am going to measure Jerusalem, to see how wide and how long it is.” Then the angel who was with me went to meet a second angel who was coming toward him. The other angel said, “Hurry, and say to that young man, ‘Jerusalem will someday be so full of people and livestock that there won’t be room enough for everyone! Many will live outside the city walls. Then I, myself, will be a protective wall of fire around Jerusalem, says the LORD. And I will be the glory inside the city!’”
