That the hippopotamus was known to the ancient Hebrews is certain. After their sojourn in Egypt they had necessarily become familiarized with it; and if, as most commentators believe, the date of the Book of Job be subsequent to the liberation of the Israelites, there is no difficulty in assuming that Job and his companions were well acquainted with the animal. Even if the book be of an earlier date, it is still possible that the hippopotamus may, in those days, have lived in rivers where it is now as much extinct as it is in England. Mr. Tristram remarks on this point: "No hippopotamus is found in Asia, but there is no reason for asserting that it may not have had an eastern range as far as Palestine, and wallowed in the Jordan; for its bones are found in the débris of the rivers of Algeria, flowing into the Mediterranean, when tradition is quite silent as to its former existence."
THE HIPPOPOTAMUS.
There is no doubt that the hippopotamus and the urus were the two largest animals known to the Jews, and it is probably on that account that the former received the name of Behemoth.
Assuming, therefore, that the Behemoth is identical with the hippopotamus, we will proceed with the description.
"He eateth grass like the ox." The word which is here rendered "grass" is translated in Numb. xi. 5 as "leeks." It means, something that is green, and is probably used to signify green herbage of any description. Now it is perfectly true of the hippopotamus that it eats grass like an ox, or like cattle, as the passage may be translated. In order to supply its huge massive body with nourishment, it consumes vast quantities of food. The mouth is enormously broad and shovel-shaped, so as to take in a large quantity of food at once; and the gape is so wide, that when the animal opens its jaws to their full extent it seems to split its head into two nearly equal portions. This great mobility of jaw is assisted by the peculiar form of the gape, which takes a sudden turn upwards, and reaches almost to the eyes.
