The document summarizes chapters 11 and 12 of the book of Exodus from the Bible. It describes how God told Moses he would kill all the firstborn sons of Egypt as the final plague, which caused a great cry. It then details how God instituted the Passover, in which the Israelites were instructed to sacrifice lambs and put their blood on their doorposts to be passed over. The summary connects this story to Jesus as the ultimate fulfillment as our Passover who was sacrificed for our sins.
