Matthew Poole and continuators on Proverbs 30:31

31 A grey-hound , an he-goat also, and a king, against whom there is no rising up .

Called in Hebrew, girt in the loins, either because its loins are slender, and as it were girt up into a little compass, and right or well trussed up: or because of its great agility and swiftness, for the girding of the loins was used for expedition in going or working. Or, as it is rendred by others, an Horse, to wit, a War▪horse, having his Armour girt about him, and marching to the battle, which he doth with great Majesty and Courage, as God himself observes at large, Iob 39. 19, &c.

Which marcheth in the head of the flock in grave and stately manner, conducting them with great courage and resolution, and being ready to fight for them, either with beasts or men that oppose him. Whence great Captains are oft compared to he-goats, as Isa. 14. 9. Ier. 50. 8. Dan. 8. 5, 21. Zech. 10. 3.

A mighty and victorious King, whose power none can withstand, who therefore goeth hither and thither, and proceedeth in his affairs with invincible Courage and Majesty. But this place, with the variation of one Hebrew point, reading ammo for immo, may be rendred, as a very learned man observes, a King and his People with him, a King when he hath the Hearts and Hands of his People going along with him in his undertakings.
