Zechariah 1:8-11

8I saw by night, and behold a man riding upon a red horse, and he stood among the myrtle trees that were in the bottom; and behind him were there red horses, speckled, and white.1 9Then said I, O my lord, what are these? And the angel that talked with me said to me, I will show thee what these are . 10And 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. 11And 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.
