Zechariah 1:9-11

Then said I, O my lord, what are these? And the angel that talked with me said unto me, I will shew thee what these be. And the man that stood among the myrtle trees answered and said, These are they whom the LORD hath sent to walk to and fro through the earth. And they answered the angel of the LORD that stood among the myrtle trees, and said, We have walked to and fro through the earth, and, behold, all the earth sitteth still, and is at rest.
