What does Exodus 8:1 mean?
Pharaoh has ignored repeated requests (Exodus 5:1–4), a miraculous sign (Exodus 7:10–13), and a catastrophic, miraculous plague (Exodus 7:20–23). Now Moses—through Aaron (Exodus 4:14–16; 7:1–2)—delivers another demand that the Hebrews be freed. This request will be rejected, as well; and the Lord will follow through on another threat to send disaster on Egypt (Exodus 8:2–6).The impending plague will involve frogs (Exodus 8:2–4) swarming away from the corrupted Nile waters (Exodus 7:24–25). Pharaoh's magicians will be able to summon frogs, but not drive them away (Exodus 8:7–8). Scripture is not specific about the timing of this next plague in relation to the first. Some of the plagues may have overlapped, or they may have all happened in sequence. It may have been that the corruption of the Nile drove insects and frogs into Egyptian cities (Exodus 8:3).
