Ezekiel 10:21
Every one had four faces apiece, and every one four wings; and the likeness of the hands of a man was under their wings. Every one had four faces apiece, and every one four wings; and the likeness of the hands of a man was under their wings.
The fourfold faces and wings with human-like hands beneath them show a divine hand actively directing every agent. That hand imposes perfect order, placing each prepared instrument exactly where it belongs and guiding its action. Out of that ordering comes harmonious cooperation, so all the varied instruments work together in unity.
