Exodus 7:14-25 - Plague One: Blood
14 And Jehovah said to Moses, Pharaoh's heart is hardened. He refuses to let the people go. 15 You go to Pharaoh in the morning. Lo, he goes out to the water. And you shall stand by the river's brink until he comes. And you shall take in your hand the rod which was turned to a snake. 16 And you shall say to him, Jehovah, the God of the Hebrews has sent me to you, saying, Let My people go so that they may serve Me in the wilderness. And, behold, until now you would not hear. 17 Thus says Jehovah, In this you shall know that I am Jehovah. Behold! I will smite with the rod that is in my hand upon the waters in the river, and they shall be turned to blood. 18 And the fish in the river shall die, and the river shall stink. And the Egyptians shall hate to drink of the water of the river.
19 And Jehovah spoke to Moses, Say to Aaron, Take your rod, and stretch out your hand upon the waters of Egypt, upon their streams, upon their canals, and upon their pools, and upon every reservoir of their waters, that they may become blood. And blood shall be throughout all the land of Egypt, both in wooden and in stone vessels.
20 And Moses and Aaron did so, as Jehovah commanded. And he lifted up the rod and struck the waters that were in the river, in the sight of Pharaoh and in the sight of his servants. And all the waters in the river were turned to blood. 21 And the fish in the river died; and the river stank, and the Egyptians could not drink of the water of the river. And there was blood throughout all the land of Egypt.
22 And the magicians of Egypt did so with their secret arts. And Pharaoh's heart was hardened, and he did not listen to them, as Jehovah had said. 23 And Pharaoh turned and went into his house; And he did not set his heart to this also. 24 And all the Egyptians dug all around the river for water to drink, for they could not drink of the water of the river. 25 And seven days were completed after Jehovah had stricken the river.
