I choose the tenth plague because I believe it was the worst. In this plague, the firstborn of the people and cattle of Egypt die, but the Israelites are spared. God sent this plague upon Egypt because Pharaoh did not do anything during the first nine plagues so God had to do one more thing to free his people. He told everyone that he was going to kill the firstborn of every household and the only way to stop it was to put lambs blood on the doorframe. Some of the affects on Egypt were that there was an outcry of sadness throughout the empire which was sad but also a happy thing because the Israelites were set free.
