עָרֹב m., a species of fly, gad-fly, very troublesome to persons; so called from sucking (blood); see the root No. I. 6; Exodus 8:17, seqq.; Psalms 78:45, 105:31. LXX κυνόμυια, dog-fly, which is described by Philo, who supposes its name to be from its boldness, De Vita Mosis, t. ii. p. 101, ed. Mangeii. Almost all the Hebrew interpreters understand it to be a collection of noxious beasts, as if a miscellaneous swarm (from ערב in the signification of mixing); and so Aqu. πάμμυια; Jerome, omne genus muscarum; Luth. allerleh Ungeziefer but עָרֹב must denote some particular creature, as is all but manifest from the passage, Exodus 8:25, 27. Oedmann (Verm. Sammlungen II. p. 150) understands blatta orientalis; called in Dutch and German Kakerlacke; but which is a creature that rather devours things than stings men; contrary to the express words of Exodus 8:17.
