1 sn The outstretched arm is a bold anthropomorphism. It describes the power of God. The Egyptians will later admit that the plagues were by the hand of God (Exod 8:19).
2 tn The word נִפְלְאֹתַי (niflÿ’otay) does not specify what the intervention will be. As the text unfolds it will be clear that the plagues are intended. Signs and portents could refer to things people might do, but “wonders” only God could do. The root refers to that which is extraordinary, surpassing, amazing, difficult to comprehend. See Isa 9:6; Gen 18:14; Ps 139:6.
3 sn The two uses of the root שָׁלָח (shalakh) in this verse contribute to its force. When the Lord “sends” (Qal) his hand, Pharaoh will “send” (Piel) the Israelites out of Egypt.
4 tn The emphasis on sequence is clear because the form is the perfect tense with the vav consecutive.
sn The use of the verb “to know” (יָדַע, yada’) underscores what was said with regard to 6:3. By the time the actual exodus took place, the Egyptians would have “known” the name Yahweh, probably hearing it more than they wished. But they will know – experience the truth of it – when Yahweh defeats them.
5 sn This is another anthropomorphism, parallel to the preceding. If God were to “put” (נָתַן, natan), “extend” (נָטָה, nata), or “reach out” (שָׁלַח, shalakh) his hand against them, they would be destroyed. Contrast Exod 24:11.
6 sn The third plague is brief and unannounced. Moses and Aaron were simply to strike the dust so that it would become gnats. Not only was this plague unannounced, but also it was not duplicated by the Egyptians.
7 tn The verb is the perfect tense with vav (ו) consecutive, meaning “and it will be.” When הָיָה (hayah) is followed by the lamed (ל) proposition, it means “become.”
8 tn The noun is כִּנִּים (kinnim). The insect has been variously identified as lice, gnats, ticks, flies, fleas, or mosquitoes. “Lice” follows the reading in the Peshitta and Targum (and so Josephus, Ant. 2.14.3 [2.300]). Greek and Latin had “gnats.” By “gnats” many commentators mean “mosquitoes,” which in and around the water of Egypt were abundant (and the translators of the Greek text were familiar with Egypt). Whatever they were they came from the dust and were troublesome to people and animals.
9 tn The verb, “and they will return,” is here subordinated to the imperative preceding it, showing the purpose of that act.
