What does Exodus 7:16 mean?
Moses is to deliver another message to Pharaoh, king of Egypt. God has already demanded the release of Israel from Egyptian slavery (Exodus 1:11–14; 5:1–3). Pharaoh refused (Exodus 5:4). He has ignored a miraculous sign (Exodus 7:10–13). Now the demand is repeated, as Pharaoh goes to the Nile river in the morning (Exodus 7:14–15). This is something the Lord expected (Exodus 3:18–20), knowing that Pharaoh would refuse even the smallest request for Israelite freedom.Moses will explain that the terrible plague about to occur is meant to prove that the God making these demands is real (Exodus 7:17–18). Egypt will suffer for seven days (Exodus 7:25) and be forced to dig for water (Exodus 7:24), because the river and all surface waters will be turned into undrinkable, decomposing blood (Exodus 7:17–18).
