John Gill Commentary Zechariah 1:9

"Then said I, O my lord, what are these? And the angel that talked with me said unto me, I will show thee what these are." — Zechariah 1:9 (ASV)

Then said I, O my Lord These are the words of the Prophet Zechariah to the angel that showed him this vision: what are these? what is the meaning of this vision? particularly who are meant by the horses, red, speckled, and white, and those upon them?

And the angel that talked with me; who seems to be different from the Angel of the Lord, the man among the myrtle trees, (Zechariah 1:8Zechariah 1:10Zechariah 1:11) he was one of the ministering spirits; see (Revelation 17:1) (21:9): said unto me, I will show you what these [be]; that is, give an interpretation of the vision, and point out the persons intended by the horses.
