Zechariah 1:9-11

“What are these, my lord?” I asked. And the angel who was speaking with me replied, “I will show you what they are.”

Then the man standing among the myrtle trees explained, “They are the ones the LORD has sent to patrol the earth.”

And the riders answered the angel of the LORD who was standing among the myrtle trees, “We have patrolled the earth, and behold, all the earth is at rest and tranquil.”
