John Calvin Commentary Ezekiel 1:17

"When they went, they went in their four directions: they turned not when they went." — Ezekiel 1:17 (ASV)

What he had already explained he now repeats for the sake of confirmation, that they went upon their four sides — that is, each living creature proceeded straight forward; the words they turned not refer to their perseverance; not that they exceeded the appointed space, but because they went forward to their object without interruption. I touch but lightly now on what has already been sufficiently explained.
