He moveth his tail like a cedar Though the tail be but short, both in the elephant, and in the hippopotamus; yet, when it is erected, it is exceeding stiff and strong. The sinews of his stones, &c. Rather, of his thighs, as the Hebrew may be rendered. The thighs and feet of the river- horse are so sinewy and strong that one of them is able to break or overturn a large boat.
