Charles Ellicott Commentary Zechariah 6:5

"And the angel answered and said unto me, These are the four winds of heaven, which go forth from standing before the Lord of all the earth." — Zechariah 6:5 (ASV)

Spirits.—Better, winds.

Which go forth.—Better, going forth. “Winds,” from which He makes His messages (Psalms 104:4), are most appropriately used here as symbolic of the working of God’s Spirit. (Daniel 7:21; John 3:8.) Here the words of the angel-interpreter pass imperceptibly into the prophet’s own description of the scene.

From standing is correct; but the Septuagint has παραστῆναι, “to stand by.”
