29. The plague of death:

Hashem told Moshe that He will bring one last plague to Pharaoh and Egypt, and Pharaoh will then capitulate completely and let you go and even force you out of Egypt.

Leaving with wealth: Hashem told Moshe that he should speak to the Jewish people and inform them [of the imminent exodus and] that each person should request from their [Egyptian] neighbor gold and silver vessels. Hashem granted the nation favor in the eyes of the Egyptians, and so too Moshe became very great in the eyes of Pharaoh and his servants.

Moshe warns Pharaoh of Makas Bechoros: [During the last meeting of Moshe with Pharaoh] Moshe told Pharaoh that Hashem said that at approximately midnight He will go amidst Egypt and smite every first born in the land of Egypt to death, from the firstborn of Pharaoh who is the prince until the firstborn of the slave woman, as well as all firstborn animals. There will be a great outcry in the entire land of Egypt, of which the liking there never was and will never be seen again. However, the Jewish people will remain safe and a dog will not bark against man or animal, so that you see that I have distinguished between the Jewish people and Egypt. Your servants will then all come down and bow to me asking us to leave, and afterwards we shall leave. Moshe left Pharaoh’s presence in burning anger. Hashem told Moshe that Pharaoh would not listen to him in order so He can increase His wonders in the land of Egypt. Moshe and Aaron performed all these miracles before Pharaoh, and Hashem strengthened his heart and he did not let them go.
