Matthew Poole and continuators on Job 39:21

21. He paweth in the valley , and rejoyceth in his strength : he goeth on to meet the armed men ▪

Or, He diggeth. Through courage and wantonness he cannot stand still, but is beating, as it were, digging up the Earth with his feet.

This he adds partly because the ground being there more plain and smooth, he hath the better conveniency for his praunsing and pawing with his feet, which in hilly and uneven ground he cannot so well do, and partly because Battels use to be pitched in Valleys or low grounds, especially Horse Battels

Making semblance of great pride and complacency in it.

With great readiness and undaunted courage.

Marginal references: Or, his see[illegible: 1+ letters] dig.; Heb. the Armour.
