John Wesley on Ezekiel 1:12

Straight - Which way soever they went, each living creature had one face looking straight forward. The spirit - The will, command, and breathing of the Spirit of God, both gave and guided their motions. Was to go - Going is attributed here to the Spirit of God, by allusion, for he who is in every place cannot properly be said to go from or to any place. Turned not - They looked not back, they turned not out of the way, they gave not over, 'till they had compleated their course.
