ANSWER: May I suggest to you that we also can know of their existence from the fortieth chapter of the book of Job, verses fifteen through thirty-four. “Behold now behemoth, which I made with thee; he eateth grass as an ox. Lo now is strength is in his loins, and is force is in the navel of his belly. He moveth his tail like a cedar: the sinews of his stones are wrapped together. His bones are as strong pieces of brass; his bones are like bars of iron. He is the chief of the ways of God; He that made him can make His sword to approach unto him. Surely the mountains bring him forth food, where all the beasts of the field play. He lieth under the shady tress, in the covert of the reed, and fens. The shady trees cover him with their shadow; the willows of the brook compass him about. Behold he drinketh up a river, and hasteth not; he trusteth that he can draw Jordan up into his mouth. He taketh it with his eyes; his nose pierces through snares.” Some have suggested that the “behemoth” is an elephant, but in light of verse seventeen the suggestion is without merit, because the creature here discussed “moveth his tail like a cedar.” The tail of an elephant is nothing but a wisp!
