The havoc which such an animal can make among growing crops may be easily imagined. It is fond of leaving the river, and forcing its way into cultivated grounds, where it eats vast quantities of green food, and destroys as much as it eats, by the trampling of its heavy feet. Owing to the width of the animal, the feet are placed very far apart, and the consequence is that the hippopotamus makes a double path, the feet of each side trampling down the herbage, and causing the track to look like a double rut, with an elevated ridge between them. Some little difficulty has been made respecting the passage in verse 20, "Surely the mountains bring him forth food." Commentators ignorant of the habits of the hippopotamus, and not acquainted with the character of the country where it lives, have thought that the animal only lived in the rivers, and merely found its food along its banks, or at most upon the marshes at the river-side. The hippopotamus, say they, is not a dweller on the mountains, but an inhabitant of the river, and therefore this passage cannot rightly be applied to the animal. Now, in the first place, the word _harim_, which is translated as "mountains" in the Authorized Version, is rendered as "hills" by many Hebraists. Moreover, as we know from many passages of Scripture, the word "mountain" is applied to any elevated spot, without reference to its height. Such places are very common along the banks of the Nile, and are employed for the culture of vegetables, which would not grow properly upon the flat and marshy lands around them. These spots are very attractive to the hippopotamus, who likes a change of diet, and thus finds food upon the mountains. In many parts of Egypt the river runs through a mountainous country, so that the hills are within a very short distance of the water, and are easily reached by the hippopotamus. The Talmudical writers exaggerated, after their custom, the dimensions, voracity, and other attributes of the Behemoth. They said that the animal devoured daily the herbage of a thousand hills, but that, in order to prevent the devastation of the world which such voracity would occasion, the herbage was miraculously renewed every night. Only two of the Behemoth were ever created, and, lest they should increase in numbers, and destroy every green thing on the face of the earth, they were made incapable of propagating their kind. There are other legends of the Behemoth too puerile to be narrated. We will now proceed to the next verse. After mentioning that the Behemoth can eat grass like an ox, and finds its food upon the hills, the sacred writer proceeds to show that in its moments of repose it is an inhabitant of the rivers and marshy ground: "He lieth under the shady trees, in the covert of the reed, and fens. "The shady trees cover him with their shadow; the willows of the brook compass him about."
