Job 39:21 - Clarke's commentary and critical notes on the Bible

He paweth in the valley, and rejoiceth in his strength: he goeth on to meet the armed men. He paweth in the valley - יחפרו yachperu, "they dig in the valley," i.e., in his violent galloping, in every pitch of his body, he scoops up sods out of the earth. Virgil has seized this idea also, in his cavat tellurem; "he scoops out the ground." See before.
