Exodus 8:21

If you do not release ¹  my people, then I am going to send ²  swarms of flies ³  on you and on your servants and on your people and in your houses. The houses of the Egyptians will be full of flies, and even the ground they stand on. ⁴ 

Ps 78:45; Ps 105:31; Isa 7:18

¹ tn The construction uses the predicator of nonexistence – אֵין (’en, “there is not”) – with a pronominal suffix prior to the Piel participle. The suffix becomes the subject of the clause. Heb “but if there is not you releasing.”

² tn Here again is the futur instans use of the participle, now Qal with the meaning “send”: הִנְנִי מַשְׁלִיחַ (hinni mashliakh, “here I am sending”).

³ tn The word עָרֹב (’arov) means “a mix” or “swarm.” It seems that some irritating kind of flying insect is involved. Ps 78:45 says that the Egyptians were eaten or devoured by them. Various suggestions have been made over the years: (1) it could refer to beasts or reptiles; (2) the Greek took it as the dog-fly, a vicious blood-sucking gadfly, more common in the spring than in the fall; (3) the ordinary house fly, which is a symbol of Egypt in Isa 7:18 (Hebrew זְבוּב, zÿvuv); and (4) the beetle, which gnaws and bites plants, animals, and materials. The fly probably fits the details of this passage best; the plague would have greatly intensified a problem with flies that already existed.

⁴ tn Or perhaps “the land where they are” (cf. NRSV “the land where they live”).
