Exodus 11:9-10
Context11:9 The Lord said to Moses, “Pharaoh will not listen to you, so that my wonders 1 may be multiplied in the land of Egypt.”
11:10 So Moses and Aaron did all these wonders before Pharaoh, but the Lord hardened Pharaoh’s heart, and he did not release the Israelites from his land.
1 sn The thought is essentially the same as in Exod 7:3-4, but the wonders, or portents, here refer to what is yet to be done in Egypt.
