4. One of the cherubim reached him a handful of fire from the midst of the living creatures. The prophet, when he first saw this vision, observed that there were burning coals of fire, and lamps, that went up and down among the living creatures (ch. i. 13); thence this fire was taken, v. 7. The spirit of burning, the refiner's fire, by which Christ purifies his church, is of a divine original. It is by a celestial fire, fire from between the cherubim, that wonders are wrought. The cherubim put it into his hand; for the angels are ready to be employed by the Lord Jesus and to serve all his purposes.
