A greyhound. — It is very doubtful what animal is meant here as being “girt [i.e., slender] in the loins.” Several have been suggested, e.g., the horse, zebra, cock; but the rendering of the Authorised Version is as probable as any.
A king, against whom there is no rising up. — Who marches with resistless force, trampling on his conquered foes. (Comp. the description of the march of the Assyrians, Isaiah 37:24 sqq.; comp. also Isaiah 63:1 sqq. and Joel 2:2 sqq.) It has been proposed to translate these words also as “a king with whom is [i.e., followed by] his people,” in much the same sense.
