Extremely enigmatic if not esoteric. This is how the prophecy of Zechariah is in its context.

The truth behind the prophetic visions of Zechariah may not be fully understood; only and until the coming of Elijah the Prophet. As it deals with the entire period from his own day until the End of Days.

Call to repentance — to return to Hashem. That in turn Hashem will return.

Test of sincerity to your service, devotion, fear and love of Hashem you who profess publicly, but do otherwise in private.

Jerusalem. Truth. Righteousness.

The rebuilding of the Temple. The hope of glad tidings for Hashem’s dwelling with His people — the righteous Jews and Gentiles.

Hashem will be One and His Name will be One.

Not through army, neither strength, but through the spirit of Hashem, Master of Legions.
