What does Exodus chapter 10 mean?
God sent Moses to deliver a command to the pharaoh of Egypt: release the captive Hebrew people (Exodus 1:11–14; 3:7–10, 18–22). Despite hearing this command many times (Exodus 5:1; 7:16; 8:1, 20; 9:1, 13), the king is stubborn (Exodus 5:2; 7:13–14, 22; 8:15, 19, 32; 9:7, 34). This defiance has led to seven catastrophes which have battered the nation (Exodus 7:21; 8:6, 17, 24; 9:6, 10, 24). After the most recent plague, Pharaoh once again broke his word about releasing the Israelites (Exodus 9:34–35). After choosing rebellion so many times (Proverbs 29:1), Pharaoh will now be used as an illustration of divine judgment (Exodus 4:21), with no meaningful ability to repent.The Lord tells Moses that Pharaoh will never agree to release the Israelites. Instead, he will be used to demonstrate the Lord's power to all the people of earth and for all of history (Exodus 3:20). God's purpose in these plagues has not been petty revenge. Instead, these events are opportunities to recognize His power and act accordingly (Exodus 10:1–2).
As commanded, Moses and Aaron (Exodus 4:14–16) rebuke Pharoah for his pride and stubbornness. They repeat the Lord's command to release the Hebrews. This comes with the threat of an eighth disaster. If Pharoah will not free God's people, Egypt will experience the worst locust plague the nation has ever seen. Everything which managed to survive the recent hailstorm (Exodus 9:31–32) will be lost (Exodus 10:3–6).
Locusts are a form taken on by common grasshoppers. These insects are normally reserved and solitary. Under certain conditions, they breed a generation with unusual traits. Now called "locusts," they are compelled to swarm in dense groups. They are aggressive, quick to breed, and insatiable eaters. Swarms of locusts can join or grow into clouds the size of entire nations. Called "plagues," even outside the Bible, hordes of locusts can devour an entire region's vegetation—including human crops—within hours or days before moving on to the next area. Further, the insects are noisy, disruptive, and filthy. Pharaoh's advisors are sensibly terrified of facing such an event. They plead with their king to negotiate with Moses; their plan is to let only the Israelite men leave (Exodus 10:7).
Pharoah's attempt to bargain immediately fails. Both he and Moses know that if some Israelites are kept in Egypt, the others will be reluctant to leave. If all the Hebrews go, none of them are coming back into slavery. Moses makes it clear that every Israelite must be freed to serve God. Pharaoh makes a snide remark about Yahweh's favor (Exodus 3:15) and angrily dismisses Moses (Exodus 10:8–11).
Following the Lord's command, Moses gestures with his staff to trigger the plague of locusts. Overnight, an east wind brings the worst locust infestation Egypt will ever experience. The insects are so numerous that they blot out sunlight and cover every surface. The locusts eat everything plant-based in the region, leaving nothing (Exodus 10:12–15).
In a panic, Pharaoh summons Moses and Aaron to plead for relief, claiming that what he has done is sinful. Pharaoh asks for forgiveness. Moses prays on the king's behalf, and God reverses the winds to drive every single locust out of the nation. Yet Pharaoh, under God's judgment for his constant disobedience (Exodus 4:21), still refuses to release the people (Exodus 10:16–20).
This leads to another divine demonstration. God sends three days of darkness on the Egyptians. This might have been a supernatural blackness, or a blocking of the sun by clouds, sandstorm, or other means. The darkness is so deep, and possibly so terrifying, that the Egyptians huddle in their homes without meeting or seeing one another. To highlight the lesson, the land of Goshen (Genesis 47:6) is spared from this event (Exodus 10:21–23).
Rather than submit, Pharaoh again tries to bargain. Moses rejects the offer to take the Israeli people but leave their livestock. This seems to push Pharaoh over the edge. He threatens to kill Moses if the two of them ever meet again. Moses replies with what amounts to a calm, possibly sarcastic shrug (Exodus 10:24–29).
This will lead to Moses announcing the final, most devastating plague (Exodus 11:4).
