Charles Ellicott Commentary Ezekiel 43:6

"And I heard one speaking unto me out of the house; and a man stood by me." — Ezekiel 43:6 (ASV)

I heard him speaking. Although the pronoun is not expressed in the original, there can be no question that God Himself spoke directly to the prophet, as in Ezekiel 44:2, 5, 9, and so on. “The man” is without the article in the Hebrew, which leaves it uncertain whether the same being is meant who had previously guided the prophet; but as measurements were also made by this guide (Ezekiel 47:3–5), he was probably the same.
