Ezekiel 3:12

I heard behind me - The commission having been given, and the prophet transported to the place of his ministry, the chariot of the vision passes away with the proper tokens Ezekiel 1:24. A voice from above the firmament is now heard proclaiming the divine glory.

From his place - The place where the glory of the Lord had revealed itself in the vision. The words are to be joined to “saying:” put a comma after Lord.
