Exodus 5:3

5:3 And they said, “The God of the Hebrews has met with us. Let us go a three-day journey ¹  into the desert so that we may sacrifice ²  to the Lord our God, so that he does not strike us with plague or the sword.” ³ 

Exodus 8:21

8:21 If you do not release ⁴  my people, then I am going to send ⁵  swarms of flies ⁶  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. ⁷ 

[5:3]  ¹ tn The word “journey” is an adverbial accusative telling the distance that Moses wanted the people to go. It is qualified by “three days.” It is not saying that they will be gone three days, but that they will go a distance that will take three days to cover (see Gen 31:22-23; Num 10:33; 33:8).

[5:3]  ² tn The purpose clause here is formed with a second cohortative joined with a vav (ו): “let us go…and let us sacrifice.” The purpose of the going was to sacrifice.

[5:3]  ³ sn The last clause of this verse is rather unexpected here: “lest he meet [afflict] us with pestilence or sword.” To fail to comply with the summons of one’s God was to invite such calamities. The Law would later incorporate many such things as the curses for disobedience. Moses is indicating to Pharaoh that there is more reason to fear Yahweh than Pharaoh.

[8:21]  ⁴ 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]  ⁵ 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]  ⁶ 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]  ⁷ tn Or perhaps “the land where they are” (cf. NRSV “the land where they live”).
