Exodus 10:4

To punish this obstinate refusal, Jehovah would bring locusts in such dreadful swarms as Egypt had never known before, which would eat up all the plants left by the hail, and even fill the houses. "They will cover the eye of the earth." This expression, which is peculiar to the Pentateuch, and only occurs again in Exo 10:15 and Num 22:5, Num 22:11, is based upon the ancient and truly poetic idea, that the earth, with its covering of plants, looks up to man. To substitute the rendering "surface" for the "eye," is to destroy the real meaning of the figure; "face" is better. It was in the swarms that actually hid the ground that the fearful character of the plague consisted, as the swarms of locusts consume everything green. "The residue of the escape" is still further explained as "that which remaineth unto you from the hail," viz., the spelt and wheat, and all the vegetables that were left (Exo 10:12 and Exo 10:15). For "all the trees that sprout" (Exo 10:5), we find in Exo 10:15, "all the tree-fruits and everything green upon the trees."

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.).

10:4 These locusts were not the insects called locusts in North America, but a form of migratory grasshopper. Swarming out of desert regions, they could devastate large areas of land, devouring all the plant life before them.
