Ezekiel 1:11

11. Their wings were in as perfect repose as their faces. Their two uplifted wings, although being used for flight (Ezekiel 1:24), were quiet as those of a bird sailing without effort through the air. Each pair of wings was uplifted to the same plane, so that the wings, though “spread apart,” or “separated,” as the Hebrew states, yet seemed to be joined to each other and thus to form a sort of platform for the crystal firmament on which rested Jehovah’s throne (Ezekiel 1:22-23). A private note from a well-known English Assyriologist says: “The figures of the Igigi, or ‘spirits of heaven,’ found at Nineveh are always represented with two pairs of wings, one pair up and one pair down, signifying that the spirit was at rest, yet watchful.”
