Zechariah 1:8-10

8In a vision during the night, I saw a man sitting on a red horse that was standing among some myrtle trees in a small valley. Behind him were riders on red, brown, and white horses.

9I asked the angel who was talking with me, “My lord, what do these horses mean?” “I will show you,” the angel replied.

10The rider standing among the myrtle trees then explained, “They are the ones the Lord has sent out to patrol the earth.”
