Keluaran 8:2

8:2 But if you refuse to release them, then I am going to plague ¹  all your territory with frogs. ² 

Keluaran 8:21

8:21 If you do not release ³  my people, then I am going to send ⁴  swarms of flies ⁵  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. ⁶ 

[8:2]  ¹ tn The construction here uses the deictic particle and the participle to convey the imminent future: “I am going to plague/about to plague.” The verb נָגַף (nagaf) means “to strike, to smite,” and its related noun means “a blow, a plague, pestilence” or the like. For Yahweh to say “I am about to plague you” could just as easily mean “I am about to strike you.” That is why these “plagues” can be described as “blows” received from God.

[8:2]  ² tn Heb “plague all your border with frogs.” The expression “all your border” is figurative for all the territory of Egypt and the people and things that are within the borders (also used in Exod 10:4, 14, 19; 13:7).

[8:2]  sn This word for frogs is mentioned in the OT only in conjunction with this plague (here and Pss 78:45, 105:30). R. A. Cole (Exodus [TOTC], 91) suggests that this word “frogs” (צְפַרְדְּעִים, tsÿfardÿ’im) may be an onomatopoeic word, something like “croakers”; it is of Egyptian origin and could be a Hebrew attempt to write the Arabic dofda.

[8:21]  ³ 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.”

[8:21]  ⁴ 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”).

[8:21]  ⁵ 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.

[8:21]  ⁶ tn Or perhaps “the land where they are” (cf. NRSV “the land where they live”).
