Charles Ellicott 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)

O my lord. —This is addressed to the angel that talked with me, or, perhaps, in me, depending on whether we regard him as fulfilling the role of the Virgil of Dante, or the Daimon of Socrates (but, see Lawes’ History of Philosophy). Septuagint, ὁ λαλῶν ἐν ἐμοί. This is the angel-interpreter, whose office it was to interpret the visions (Zechariah 1:18; Zechariah 2:3; Zechariah 4:1; Zechariah 4:4–5; Zechariah 5:5–10; Zechariah 6:4), and who is often referred to simply as “he.”

I will show you. —namely, by the word of the man who stood among the myrtles.
