The Rabbis have taught that there are six sorts of fire:--(1.) Fire that
eats but drinks not, i.e., common fire; (2.) fire that drinks but does
not eat, i.e., a fever; (3.) fire that eats and drinks, i.e., Elijah, as
it is written (1 Kings xviii. 38), "And licked up the water that was in
the trench;" (4.) fire that burns up moist things as soon as dry, i.e.,
the fire on the altar; (5.) fire that counteracts other fire, i.e., like
that of Gabriel; (6.) fire that consumes fire, for the Master has said
(Sanhed., fol. 38, col. 2), "God stretched out His finger among the
angels and consumed them," i.e., by His own essential fire.
