Zechariah 2:3-5

And, behold, the angel that talked with me went forth, and another angel went out to meet him, and said unto him, Run, speak to this young man, saying, Jerusalem shall be inhabited as villages without walls, by reason of the multitude of men and cattle therein. For I, saith Jehovah, will be unto her a wall of fire round about, and I will be the glory in the midst of her.
