Psalms 78:45

²¹Else, if you will not let my people go, behold, I will send swarms of flies on you, and on your servants, and on your people, and into your houses. The houses of the Egyptians shall be full of swarms of flies, and also the ground they are on. ²²I will set apart in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there, to the end you may know that I am the LORD on the earth. ²³I will put a division between my people and your people. This sign shall happen by tomorrow.”’” ²⁴The LORD did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants’ houses. In all the land of Egypt the land was corrupted by reason of the swarms of flies.

³⁰Their land swarmed with frogs, even in the rooms of their kings. ³¹He spoke, and swarms of flies came, and lice in all their borders.

²If you refuse to let them go, behold, I will plague all your borders with frogs. ³The river will swarm with frogs, which will go up and come into your house, and into your bedroom, and on your bed, and into the house of your servants, and on your people, and into your ovens, and into your kneading troughs. ⁴The frogs shall come up both on you, and on your people, and on all your servants.”’” ⁵The LORD said to Moses, “Tell Aaron, ‘Stretch out your hand with your rod over the rivers, over the streams, and over the pools, and cause frogs to come up on the land of Egypt.’” ⁶Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt. ⁷The magicians did the same thing with their enchantments, and brought up frogs on the land of Egypt.

⁸Then Pharaoh called for Moses and Aaron, and said, “Entreat the LORD, that he take away the frogs from me and from my people; and I will let the people go, that they may sacrifice to the LORD.”

⁹Moses said to Pharaoh, “I give you the honor of setting the time that I should pray for you, and for your servants, and for your people, that the frogs be destroyed from you and your houses, and remain in the river only.”

¹⁰Pharaoh said, “Tomorrow.” Moses said, “Let it be according to your word, that you may know that there is no one like the LORD our God.

¹¹The frogs shall depart from you, and from your houses, and from your servants, and from your people. They shall remain in the river only.”

¹²Moses and Aaron went out from Pharaoh, and Moses cried to the LORD concerning the frogs which he had brought on Pharaoh. ¹³The LORD did according to the word of Moses, and the frogs died out of the houses, out of the courts, and out of the fields. ¹⁴They gathered them together in heaps, and the land stank. ¹⁵But when Pharaoh saw that there was a respite, he hardened his heart, and didn’t listen to them, as the LORD had spoken.

³The second angel poured out his bowl into the sea, and it became blood as of a dead man. Every living thing in the sea died.
