Ezekiel 1:9

Their wings were joined one to another - When their wings were extended, they formed a sort of canopy level with their own heads or shoulders; and on this canopy was the throne, and the "likeness of the man" upon it, Ezekiel 1:26.

They turned not when they went - The wings did not flap in flying, or move in the manner of oars, or of the hands of a man in swimming, in order to their passing through the air; as they glided in reference to their feet, so they soared in reference to their wings.

Two of the wings were in the act of flying, so stretched out that the extremity of each touched a wing of a neighboring living creature, similarly stretched out. This was only when they were in motion. See Ezekiel 1:24.

They went every one straight forward - The four together formed a square, and never altered their relative position. From each side two faces looked straight out, one at each corner - and so all moved together toward any of the four quarters, toward which each one had one of its four faces directed; in whatsoever direction the whole moved the four might be said all to go "straight forward."

1:9 Their wings - The wings of the two cherubim which went foremost, and the wings of the two hindermost, were joined together when they moved.Went - This explains the former words, assuring us, that every one of those living creatures are ready, and unwearied in doing the pleasure of their Creator.
