Discovery BoxExodus 8:5 
Context8:5 The Lord spoke to Moses, “Tell Aaron, ‘Extend your hand with your staff 1 over the rivers, over the canals, and over the ponds, and bring the frogs up over the land of Egypt.’”
Exodus 8:16
Context8:16 2 The Lord said to Moses, “Tell Aaron, ‘Extend your staff and strike the dust of the ground, and it will become 3 gnats 4 throughout all the land of Egypt.’”
1 sn After the instructions for Pharaoh (7:25-8:4), the plague now is brought on by the staff in Aaron’s hand (8:5-7). This will lead to the confrontation (vv. 8-11) and the hardening (vv. 12-15).
2 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.
3 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.”
4 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.
