Exodus 10:18

To show the hardened king the greatness of the divine long-suffering, Moses prayed to the Lord, and the Lord cast the locusts into the Red Sea by a strong west wind. The expression "Jehovah turned a very strong west wind" is a concise form, for "Jehovah turned the wind into a very strong west wind." The fact that locusts do perish in the sea is attested by many authorities. Gregatim sublatae vento in maria aut stagna decidunt (Pliny); many others are given by Bochart and Volney. ויּתקעהוּ: He thrust them, i.e., drove them with irresistible force, into the Red Sea. The Red Sea is called סוּף ים, according to the ordinary supposition, on account of the quantity of sea-weed which floats upon the water and lies upon the shore; but Knobel traces the name to a town which formerly stood at the head of the gulf, and derived its name from the weed, and supports his opinion by the omission of the article before Suph, though without being able to prove that any such town really existed in the earlier times of the Pharaohs.

The eighth and ninth of the plagues of Egypt, that of locusts and that of darkness, are recorded in this chapter. I. Concerning the plague of locusts, 1. God instructs Moses in the meaning of these amazing dispensations of his providence (Exo 10:1, Exo 10:2). 2. He threatens the locusts (Exo 10:3-6). 3. Pharaoh, at the persuasion of his servants, is willing to treat again with Moses (Exo 10:7-9), but they cannot agree (Exo 10:10, Exo 10:11). 4. The locusts come (Exo 10:12-15). 5. Pharaoh cries Peccavi - I have offended (Exo 10:16, Exo 10:17), whereupon Moses prays for the removal of the plague, and it is done; but Pharaoh's heart is still hardened (Exo 10:18-20). II. Concerning the plague of darkness, 1. It is inflicted (Exo 10:21-23). 2. Pharaoh again treats with Moses about a surrender, but the treaty breaks off in a heat (Exo 10:26, etc.).
