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 towns without walls for the multitude of men and cattle therein:

For I, saith the LORD, will be unto her a wall of fire round about, and will be the glory in the midst of her.
