Jamieson, Fausset & Brown, on Jude 1:10

“But these men blaspheme whatever things they know not: and what things soever they naturally know, like dumb beasts, in these they are corrupted.”

“(Pe2 2:12.) those things which--Greek, "all things whatsoever they understand not," namely, the things of the spiritual world. but what . . . naturally--Connect thus, "Whatever (so the Greek) things naturally (by natural, blind instinct), as the unreasoning (so the Greek) animals, they know," &c. The Greek for the former "know" implies deeper knowledge; the latter "know," the mere perception of the "animal senses and faculties."”
