Exodus 4:9

¹⁹The LORD said to Moses, “Tell Aaron, ‘Take your rod, and stretch out your hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood. There will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’”

²⁰Moses and Aaron did so, as the LORD 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 that were in the river were turned to blood. ²¹The fish that were in the river died. The river became foul. The Egyptians couldn’t drink water from the river. The blood was throughout all the land of Egypt. ²²The magicians of Egypt did the same thing with their enchantments. So Pharaoh’s heart was hardened, and he didn’t listen to them, as the LORD had spoken. ²³Pharaoh turned and went into his house, and he didn’t even take this to heart. ²⁴All the Egyptians dug around the river for water to drink; for they couldn’t drink the river water. ²⁵Seven days were fulfilled, after the LORD had struck the river.

²²Pharaoh commanded all his people, saying, “You shall cast every son who is born into the river, and every daughter you shall save alive.”

²For with whatever judgment you judge, you will be judged; and with whatever measure you measure, it will be measured to you.
