Exodus 7:20-25

20 And Moses and Aaron do so, as Jehovah hath commanded, and he lifteth up [his hand] with the rod, and smiteth the waters which [are] in the River, before the eyes of Pharaoh, and before the eyes of his servants, and all the waters which [are] in the River are turned to blood,
21 and the fish which [is] in the River hath died, and the River stinketh, and the Egyptians have not been able to drink water from the River; and the blood is in all the land of Egypt.
22 And the scribes of Egypt do so with their flashings, and the heart of Pharaoh is strong, and he hath not hearkened unto them, as Jehovah hath spoken,
23 and Pharaoh turneth and goeth in unto his house, and hath not set his heart even to this;
24 and all the Egyptians seek water round about the river to drink, for they have not been able to drink of the waters of the River.
25 And seven days are completed after Jehovah's smiting the River,

Exodus 7:20-25 Meaning and Commentary

INTRODUCTION TO EXODUS 7

Moses and Aaron are ordered to go to Pharaoh, and require the dismission of the people of Israel, but they are told before hand that Pharaoh's heart would be hardened, and would refuse to let them go, until the hand of the Lord was stretched out, and great judgments were brought down upon, Egypt, and then they should come forth, Ex 7:1-5, which orders Moses and Aaron obeyed, and their age is observed, when this was done, Ex 7:6,7 and they are bid to work a miracle, when Pharaoh should demand one, by turning a rod into a serpent, which they did; but Pharaoh's magicians doing the same in appearance, his heart was hardened, Ex 7:8-14 and then they are directed to meet him at the river, and require the same as before; and if he refused, to smite the waters of the river with the rod, and turn them into blood, which they did, Ex 7:15-21, but Pharaoh's magicians doing the same by enchantments, he did not regard it, though the plague lasted seven days, Ex 7:22-25.
