Commentaries
40:15-24 God, for the further proving of his own power, describes two vast animals, far exceeding man in bulk and strength. Behemoth signifies beasts. Most understand it of an animal well known in Egypt, called the river-horse, or hippopotamus. This vast animal is noticed as an argument to humble ourselves before the great God; for he created this vast animal, which is so fearfully and wonderfully made. Whatever strength this or any other creature has, it is derived from God. He that made the soul of man, knows all the ways to it, and can make the sword of justice, his wrath, to approach and touch it. Every godly man has spiritual weapons, the whole armour of God, to resist, yea, to overcome the tempter, that his never-dying soul may be safe, whatever becomes of his frail flesh and mortal body.
15-24. God shows that if Job cannot bring under control the lower animals (of which he selects the two most striking, behemoth on land, leviathan in the water), much less is he capable of governing the world.
behemoth—The description in part agrees with the hippopotamus, in part with the elephant, but exactly in all details with neither. It is rather a poetical personification of the great Pachydermata, or Herbivora (so "he eateth grass"), the idea of the hippopotamus being predominant. In Job 40:17, "the tail like a cedar," hardly applies to the latter (so also Job 40:20, 23, "Jordan," a river which elephants alone could reach, but see on [560]Job 40:23). On the other hand, Job 40:21, 22 are characteristic of the amphibious river horse. So leviathan (the twisting animal), Job 41:1, is a generalized term for cetacea, pythons, saurians of the neighboring seas and rivers, including the crocodile, which is the most prominent, and is often associated with the river horse by old writers. "Behemoth" seems to be the Egyptian Pehemout, "water-ox," Hebraized, so-called as being like an ox, whence the Italian bombarino.
with thee—as I made thyself. Yet how great the difference! The manifold wisdom and power of God!
he eateth grass—marvellous in an animal living so much in the water; also strange, that such a monster should not be carnivorous.
