Exodus 7:18-24

18 The fish will die, and the river will stink so much that the Egyptians will not be able to drink from it.' "
19 The Lord said to Moses, "Tell Aaron to take his stick and hold it out over all the rivers, canals, and pools in Egypt. The water will become blood, and all over the land there will be blood, even in the wooden tubs and stone jars."
20 Then Moses and Aaron did as the Lord commanded. In the presence of the king and his officers, Aaron raised his stick and struck the surface of the river, and all the water in it was turned into blood.
21 The fish in the river died, and it smelled so bad that the Egyptians could not drink from it. There was blood everywhere in Egypt.
22 Then the king's magicians did the same thing by means of their magic, and the king was as stubborn as ever. Just as the Lord had said, the king refused to listen to Moses and Aaron.
23 Instead, he turned and went back to his palace without paying any attention even to this.
24 All the Egyptians dug along the bank of the river for drinking water, because they were not able to drink water from the river.

Exodus 7:18-24 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.
