If they will not believe even these two signs or listen to your voice, you shall take some water from the Nile and pour it on the dry ground, and the water that you shall take from the Nile will become blood on the dry ground.”

Then Zipporah took a flint and cut off her son's foreskin and touched Moses' feet with it and said, “Surely you are a bridegroom of blood to me!”

So he let him alone. It was then that she said, “A bridegroom of blood,” because of the circumcision.

The First Plague: Water Turned to Blood

Then the Lord said to Moses, “Pharaoh's heart is hardened; he refuses to let the people go.

Thus says the Lord, “By this you shall know that I am the Lord: behold, with the staff that is in my hand I will strike the water that is in the Nile, and it shall turn into blood.

And the Lord said to Moses, “Say to Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt, over their rivers, their canals, and their ponds, and all their pools of water, so that they may become blood, and there shall be blood throughout all the land of Egypt, even in vessels of wood and in vessels of stone.’”

Moses and Aaron did as the Lord commanded. In the sight of Pharaoh and in the sight of his servants he lifted up the staff and struck the water in the Nile, and all the water in the Nile turned into blood.

And the fish in the Nile died, and the Nile stank, so that the Egyptians could not drink water from the Nile. There was blood throughout all the land of Egypt.

“Then they shall take some of the blood and put it on the two doorposts and the lintel of the houses in which they eat it.

The blood shall be a sign for you, on the houses where you are. And when I see the blood, I will pass over you, and no plague will befall you to destroy you, when I strike the land of Egypt.

Take a bunch of hyssop and dip it in the blood that is in the basin, and touch the lintel and the two doorposts with the blood that is in the basin. None of you shall go out of the door of his house until the morning.

For the Lord will pass through to strike the Egyptians, and when he sees the blood on the lintel and on the two doorposts, the Lord will pass over the door and will not allow the destroyer to enter your houses to strike you.

“You shall not offer the blood of my sacrifice with anything leavened, or let the fat of my feast remain until the morning.

And Moses took half of the blood and put it in basins, and half of the blood he threw against the altar.

And Moses took the blood and threw it on the people and said, “Behold the blood of the covenant that the Lord has made with you in accordance with all these words.”

and shall take part of the blood of the bull and put it on the horns of the altar with your finger, and the rest of the blood you shall pour out at the base of the altar.

and you shall kill the ram and shall take its blood and throw it against the sides of the altar.

and you shall kill the ram and take part of its blood and put it on the tip of the right ear of Aaron and on the tips of the right ears of his sons, and on the thumbs of their right hands and on the great toes of their right feet, and throw the rest of the blood against the sides of the altar.

Then you shall take part of the blood that is on the altar, and of the anointing oil, and sprinkle it on Aaron and his garments, and on his sons and his sons' garments with him. He and his garments shall be holy, and his sons and his sons' garments with him.

Aaron shall make atonement on its horns once a year. With the blood of the sin offering of atonement he shall make atonement for it once in the year throughout your generations. It is most holy to the Lord.”

“You shall not offer the blood of my sacrifice with anything leavened, or let the sacrifice of the Feast of the Passover remain until the morning.
