23. The plague of wild animals:

Hashem’s instructions to Moshe to warn Pharaoh and perform the plague: Hashem told Moshe: awaken early in the morning and greet Pharaoh by the river and tell him that Hashem demands that he let His people go so they can serve Him, and if you refuse to send them, I will send against you and your servants wild animals. The wild animals will fill the houses of Egypt and its grounds. I will distinguish on that day between the land of Goshen, on which my nation stands, by not having any wild animals there. You then shall know that I am G-d of the land.

The plague: Hashem did as he warned, and He brought a heavy mixture of wild animals to Pharaoh’s home and the home of his servants, and they caused destruction throughout the entire land

Pharaoh reaction and the ensuing negotiations: Pharaoh summoned Moshe and Aaron and told them that they may make sacrifices to their G-d in Egypt. Moshe replied that they cannot do so, as it is an abomination in Egypt to slaughter to G-d, and the Egyptians will stone us for doing so. We need to travel a three-day journey, so we can slaughter for our G-d as He will instruct us. Pharaoh replied that he will agree to send them so they could sacrifice to their Lord in the desert, so long as Moshe does not go far, and he prays for him. Moshe replied that as soon as he leaves, he will pray to Hashem on his behalf to remove the wild animals tomorrow, although Pharaoh may no longer retract his word and refuse to let the people go to sacrifice to Hashem.

Moshe prays: Moshe left his audience with Pharaoh and Davened to Hashem. Hashem did as Moshe asked for and he removed the wild animals from Pharaoh and his nation, not one remained.

Pharaoh refuses to let them go: Pharaoh hardened his heart this time as well and refused to let the people go.
