Then flew one of the seraphims unto me, having a live coal in his hand, [which] he had taken with the tongs from off the altar:
Ver. 6. Then flew one of the seraphims unto me.] Relinquit chorum illum sanctissimum ut serviat polluto; He leaveth that holy company that he may do service to a poor polluted creature! The brightest angel in heaven thinketh not himself too good to serve the saints. Heb 1:14 If there come to us at any time a messenger, one of a thousand, to declare unto us our righteousness, to be unto us a minister of reconciliation, we are to receive him as an angel of God.
Having a live coal in his hand.] A coal from the altar, shadowing the merit and Spirit of Christ purging his people from all sin. The tongs whereby this live coal of Christ's righteousness is applied to the soul is the grace of faith. Act 15:9
