Zechariah 1:8-10

8I looked out into the night and saw a man riding on a red horse. He was standing among the myrtle trees in the hollow, and behind him were red, sorrel, and white horses.

9“What are these, my lord?” I asked.

And the angel who was speaking with me replied, “I will show you what they are.”

10Then the man standing among the myrtle trees explained, “They are the ones the LORD has sent to patrol the earth.”
