Exodus 7:20

²⁹He turned their waters into blood, and killed their fish.

⁴⁴he turned their rivers into blood, and their streams, so that they could not drink.

⁹Moses said to Joshua, “Choose men for us, and go out to fight with Amalek. Tomorrow I will stand on the top of the hill with God’s rod in my hand.” ¹⁰So Joshua did as Moses had told him, and fought with Amalek; and Moses, Aaron, and Hur went up to the top of the hill. ¹¹When Moses held up his hand, Israel prevailed. When he let down his hand, Amalek prevailed. ¹²But Moses’ hands were heavy; so they took a stone, and put it under him, and he sat on it. Aaron and Hur held up his hands, the one on the one side, and the other on the other side. His hands were steady until sunset.

⁵The LORD said to Moses, “Walk on before the people, and take the elders of Israel with you, and take the rod in your hand with which you struck the Nile, and go. ⁶Behold, I will stand before you there on the rock in Horeb. You shall strike the rock, and water will come out of it, that the people may drink.” Moses did so in the sight of the elders of Israel.

⁸The second angel sounded, and something like a great burning mountain was thrown into the sea. One third of the sea became blood,

⁸“Take the rod, and assemble the congregation, you, and Aaron your brother, and speak to the rock before their eyes, that it pour out its water. You shall bring water to them out of the rock; so you shall give the congregation and their livestock drink.”

⁹Moses took the rod from before the LORD, as he commanded him. ¹⁰Moses and Aaron gathered the assembly together before the rock, and he said to them, “Hear now, you rebels! Shall we bring water out of this rock for you?” ¹¹Moses lifted up his hand, and struck the rock with his rod twice, and water came out abundantly. The congregation and their livestock drank.

¹²The LORD said to Moses and Aaron, “Because you didn’t believe in me, to sanctify me in the eyes of the children of Israel, therefore you shall not bring this assembly into the land which I have given them.”

¹⁷The LORD says, “In this you shall know that I am the LORD. Behold: I will strike with the rod that is in my hand on the waters which are in the river, and they shall be turned to blood. ¹⁸The fish that are in the river will die and the river will become foul. The Egyptians will loathe to drink water from the river.”’”

⁹When the ruler of the feast tasted the water now become wine, and didn’t know where it came from (but the servants who had drawn the water knew), the ruler of the feast called the bridegroom ¹⁰and said to him, “Everyone serves the good wine first, and when the guests have drunk freely, then that which is worse. You have kept the good wine until now!” ¹¹This beginning of his signs Jesus did in Cana of Galilee, and revealed his glory; and his disciples believed in him.
