10. Death of the Firstborn ( ): Ex. 11:112:36 This is what the Lord says: 'About midnight I will go throughout Egypt. Every firstborn son in Egypt will die, from the firstborn son of Pharaoh, who sits on the throne, to the firstborn son of the slave girl, who is at her hand mill, and all the firstborn of the cattle as well. There will be loud wailing throughout Egyptworse than there has ever been or ever will be again.'
Exodus 11:46
The tenth and final plague of Egypt was the death of all of the first born children in Egypt no one escaped, from the lowest servant to Pharaoh's own first-born son, including first-born of livestock. Before the plague, God commanded Moses to inform all the Israelites to mark lamb's blood on the doorposts on every door in which case the LORD will pass over them and not "suffer the destroyer to come into your houses and smite you" (chapter 12, v. 23), thus sparing all the Israelite first-borns in households that followed the instructions. This was the hardest blow upon Egypt and the plague that finally convinced Pharaoh to submit, and let the Israelites go.
After this, Pharaoh, furious, saddened, and afraid that he would be killed next, ordered the Israelites to go away, taking whatever they wanted. The Israelites didn't hesitate, believing that soon Pharaoh would once again change his mind; and at the end of that night Moses led them out of Egypt with "arms upraised." [30]
