Zechariah 2:1-9

And I looked up, and saw a man with a measuring line in his hand. So I said, “Where are you going?” And he said to me, “To measure Jerusalem, to see how wide it is and how long it is.” And behold, the angel who was speaking with me was going out, and another angel was coming out to meet him, and he said to the second angel, “Run, speak to that young man, saying, ‘Jerusalem will be inhabited [like villages] without walls [spreading out into the open country] because of the great number of people and livestock in it. For I,’ declares the LORD, ‘will be a wall of fire around her [protecting her from enemies], and I will be the glory in her midst.’ ” “Hear this! Flee from [Babylon] the land of the north [which shall come under judgment],” declares the LORD, “for I have scattered you like the four winds of the heavens,” declares the LORD. “Hear, Zion (Jerusalem)! Escape, you who are living with the daughter of Babylon!” For thus says the LORD of hosts, “After glory He has sent Me against the nations which plunder you—for he who touches you, touches the apple of His eye. Behold, I will wave my hand over them and they shall become plunder for their own slaves. Then you shall know (recognize, understand fully) that the LORD of hosts has sent Me.
