Zechariah 1:8-11

8 In the night I saw a man riding on a red horse! He was standing among the myrtle trees in the glen; and behind him were red, sorrel, and white horses.
9 Then I said, "What are these, my lord?" The angel who talked with me said to me, "I will show you what they are."
10 So the man who was standing among the myrtle trees answered, "They are those whom the Lord has sent to patrol the earth."
11 Then they spoke to the angel of the Lord who was standing among the myrtle trees, "We have patrolled the earth, and lo, the whole earth remains at peace."
