Charles Ellicott Commentary Zechariah 1:14

"So the angel that talked with me said unto me, Cry thou, saying, Thus saith Jehovah of hosts: I am jealous for Jerusalem and for Zion with a great jealousy." — Zechariah 1:14 (ASV)

That communed with me. —The Hebrew words are the same as those rendered elsewhere, “that spake with me.”

I am jealous. —The verb is in the perfect, like “I am returned” (Zechariah 1:16), and denotes that the Lord had already shown His jealous love for Israel in bringing them out of captivity, and that He would continue to do so in completing the restoration of Jerusalem. “The hour of darkest desolation to the Church, and of haughtiest triumph to her enemies, is often the very hour when God begins His work of judgment on the one, and returning mercy on the other” (Moore).
