Job 41:19 - Matthew Poole's English Annotations on the Holy Bible

i.e. His breathings and blowings are very hot, or flaming, as the following verses explain this. This also may seem better to agree to the crocodile, which breathes (as Aristotle affirms) like the hippopotamus, of which ancient authors affirm, that his nostrils are very large, and he breathes forth a fiery smoke like that of a furnace, than to the whale, which rather casts forth streams of water, as was noted before, than flames of fire, there being no such great heat observed in whales, nor, as far as I know, in any other fishes.
