“Behemoth” means great beasts

Behemoth: There can be little or no doubt that by this word, (Job 40:15-24) the hippopotamus is intended since all the details descriptive of the behemoth accord entirely with the ascertained habits of that animal. The hippopotamus is an immense creature having a thick and square head, a large mouth often two feet broad, small eyes and ears, thick and heavy body, short legs terminated by four toes, a short tail, skin without hair except at the extremity of the tail. It inhabits nearly the whole of Africa, and has been found of the length of 17 feet. It delights in the water, but feeds on herbage on land. It is not found in Palestine, but may at one time have been a native of western Asia.
