Zechariah 1:8, 10-11

I saw by night, and behold, a man riding on a red horse, and it stood among the myrtle trees in the hollow; and behind him were horses: red, sorrel, and white.

And the man who stood among the myrtle trees answered and said, “These are the ones whom the LORD has sent to walk to and fro throughout the earth.” So they answered the Angel of the LORD, who stood among the myrtle trees, and said, “We have walked to and fro throughout the earth, and behold, all the earth is resting quietly.”
