After the first nine plagues in Egypt, the Lord sent a tenth plague that would kill the firstborn of each household. The Israelites were commanded to do certain things to avoid this plague, including taking a male lamb without blemish and using the blood to mark the door posts of the house. They would then eat the meat of the lamb with bitter herbs and unleavened bread. This was done to symbolize Jesus Christ and His Atonement. Each year after, the Israelites would remember their deliverance from Egypt and look forward to their deliverance from sin by celebrating the Passover and eating this special meal. 

Just before His death, Jesus Christ blessed and shared bread and wine with his disciples and told them to eat and drink in remembrance of Him. We now remember Him by partaking of the sacrament each week. At Eastertime especially, we remember His great sacrifice and His miraculous resurrection which gives us hope and peace.
