Zechariah 1:9-11

I asked the angel who was talking with me, “My lord, what do these horses mean?” “I will show you,” the angel replied. The rider standing among the myrtle trees then explained, “They are the ones the LORD has sent out to patrol the earth.” Then the other riders reported to the angel of the LORD, who was standing among the myrtle trees, “We have been patrolling the earth, and the whole earth is at peace.”
