Zechariah 1:9-11

Then I said, “My lord, what are these?” And the angel who was speaking with me said to me, “I will show you what these are.” And the man who was standing among the myrtle trees answered and said, “These are those whom the LORD has sent to patrol the earth.” So they answered the angel of the LORD who was standing among the myrtle trees and said, “We have patrolled the earth, and behold, all the earth is peaceful and quiet.”
