Matthew Poole and continuators on Ezekiel 1:10

10 As for the likeness of their faces, they four had the face of a man, and the face of a lion on the right side, and they four had the face of an oxe on the left side, they four also had the face of an Eagle.

Here the Prophet doth more expressely set forth what was more darkly mentioned in the 6. verse, and describeth their faces both by the proper resemblances, and by their respect to the local differences of East and West, or right and left hand. But since such differences are in themselves of little moment, and undeterminable, unless we were certain what prospect these living Creatures stood in, whether looking to the Prophet, or to Ierusalem, or toward Babylon we shall say no more of it; what these signifie is more material. Each Face is compared to what is most excellent in its kind, Man excels in Wisdom, Lyons in Strength, the Oxe in Patience and Constancy of Labour, the Eagle in Speed, and high Flight. So in the Ministry of Angels, and Government of the World by the Providence of God, what is most excellent may be observed.
