Then Adonai told Moses, “Say to Aaron: Stretch out your hand with your staff over the rivers, canals and pools, and cause frogs to come up over the land of Egypt.”
So He said, “I will surely be with you. So that will be the sign to you that it is I who have sent you. When you have brought the people out of Egypt: you will worship God on this mountain.”
“They will listen to your voice. So you will go, you along with the elders of Israel, to the king of Egypt, and say to him: ‘Adonai, the God of the Hebrews, has met with us. Now please let us take a three-day journey into the wilderness, so that we may sacrifice to Adonai our God.’
Afterward, Moses and Aaron went and said to Pharaoh, “This is what Adonai, God of Israel, says: Let My people go, so that they may hold a feast for Me in the wilderness.”
They answered, “The God of the Hebrews has met with us. Please let us take a three-day journey into the wilderness, so we may sacrifice to Adonai our God, or else He may strike us with pestilence or with the sword.”
You are to say to him: Adonai, God of the Hebrews, has sent me to you, saying, ‘Let My people go, so they may serve Me in the wilderness,’ and behold, you have not listened.
Adonai did just so. A massive swarm of flies went into the house of Pharaoh and into his servant’s houses. All the land of Egypt was ruined because of the swarm of flies.
Then Adonai said to Moses, “Go in to Pharaoh, and tell him: This is what Adonai, the God of the Hebrews, says: ‘Let My people go, so they may serve Me.’
Then Adonai said to Joshua, “Stretch out the javelin that is in your hand toward Ai, for I will give it into your hand.” So Joshua stretched out the javelin that was in his hand toward the city.
