Passover (Pesach in Hebrew) is a Jewish festival celebrating the exodus from Egypt and the Israelites’ freedom from slavery to the Egyptians.
God “passed over” the houses of the Jews when He was slaying the firstborn of Egypt during the last of the ten plagues. The deaths of the firstborn finally breaks Pharaoh’s resistance and he literally begs the children of Israel to leave his land.
The Feast of Passover, along with the Feast of Unleavened Bread, was the first of the festivals to be commanded by God for Israel to observe (see Exodus 12). Commemorations today involve a special meal called the Seder, featuring unleavened bread and other food items symbolic of various aspects of the exodus.
The Last Supper of Jesus and His apostles was apparently a Passover seder.
By (spiritually) applying Jesus Christ’s blood to our lives by faith, we trust Him to save us from death. The Israelites who, in faith, applied the blood of the Paschal lamb to their homes become a model for us. It was not the Israelites’ ancestry or good standing or amiable nature that saved them; it was only the blood of the lamb that made them exempt from death (see John 1:29 and Revelation 5:9–10).
