Zechariah 1:9-11

Then I said, “O my lord, what are these?” And the angel who was speaking with me said, “I will show you what these are.” And the Man who stood among the myrtle trees answered and said, “These are the ones whom the LORD has sent to go throughout the earth and patrol it.” And the men on the horses answered the Angel of the LORD who stood among the myrtle trees and said, “We have gone throughout the earth [patrolling it] and behold, all the earth sits at rest [in peace and free from war].”
