Isaiah 34:7

“And the unicorns shall come down with them, &c.] With the lambs, goats, and rams; that is, either the rhinoceros, as some, there being no such creature as the unicorn; or the buffaloes, asf667 others; these “shall fall”, as the Septuagint, Syriac, and Arabic versions render it, they shall be slain, as well as the rest; meaning, that along with the common soldiers, and inferior officers, the general officers should fall; and so the Targum, “and the mighty shall be slain with them.” R. Abraham Seba saysf668 he read in a certain book, that the word here should not be read µymar, “unicorns”, but µyymwr, “the Romans shall come down”, &c.: and the bullocks with the bulls: or, as the Targum, “and…”

“unicorns--Hebrew, reem: conveying the idea of loftiness, power, and pre-eminence (see on Job 39:9), in the Bible.

“The unicorns - It is confessed, this was a beast of great strength and fierceness; and it is used in this place to signify their princes and potentates, who shall be humbled and cast down. Them - With the lambs, and goats, and rams. Fatness - With the fat of the slain sacrifices, mingled with it. Isaiah 34:8”
