Albert Barnes Commentary Ezekiel 1:24

"And when they went, I heard the noise of their wings like the noise of great waters, like the voice of the Almighty, a noise of tumult like the noise of a host: when they stood, they let down their wings." — Ezekiel 1:24 (ASV)

The voice of the Almighty – Thunder.

The voice of speech – Rendered in Jeremiah 11:16 “a great tumult.” Some take it to describe the rushing of a storm.
