Zechariah 2:2-5

2I asked, “Where are you going?” He answered me, “To measure Jerusalem to determine its width and length.”

3Then the angel who was speaking with me went out, and another angel went out to meet him.

4He said to him, “Run and tell this young man: Jerusalem will be inhabited without walls because of the number of people and animals in it.”

5The declaration of the Lord: “I myself will be a wall of fire around it, and I will be the glory within it.”
