John Trapp on Habakkuk 1:8

Verſe 8. Their horſes alſo are ſwifter then the leopards] Or Panthers, famous for their ſwiftneſſe: whence the proverb Panther â velocior. The horſe is ſo ſwift in ſervice, that the Perſians (as Pauſanias hath it) dedicated him to their god the Sun; as the ſwifteſt creature to the ſwifteſt god. See Iob. 41.20. Prov. 21.31.

and are more fierce then the evening wolves] Heb: more ſharp ſet, after that they have been held hunger bit, and empty all the day long. See Virg. Aeneid. lib. 9. ver. 59. &c. Oppian: lib. 1.3. Homo homini lupus, One man (left to himſelf) is a wolf, nay a devill to another. The Metaphor is here taken from ſharpeſt ſwords, which quickly cut.

and their horſemen ſhall ſpread themſelves] with incredible ſwiftneſſe, which in war is moſt neceſſary and uſefull, as Julus Caeſar experienced, and we in our late commotions.

and their horſemen ſhall come from far] The Jews were ſecure of the Chaldaeans, as being far remote: but that ſhall be no hinderance.

they ſhall flee as the Eagle that haſteth to eat] In ſingulis verbis pondus eſt, ſaith Druſius, Here each word hath its waight:Job. 9.26. for he that haſteth on his way is ſaid to flie, and the Eagle is ſwifter of flight then any bird, and eſpecially when ſhe haſteth to eat. Of the Eagles ſwiftneſſe why and whence, See Ambroſe Hexam: l. 1. c. 14.
