Job 39:25

“He saith among the trumpets, ha, ha, etc.] As pleased with the sound of them, rejoicing thereat, and which he signifies by neighing; and he smelleth the battle afar off; which respects not so much the distance of place as of time; he perceives beforehand that it is near, by the preparations making for it, and particularly by what follows; so Pliny f1416 says of horses, they presage a fight.
