Essentially Sacrificial
Two timetables were about to fit together. About 1,500 years earlier, the blood of a sacrificed lamb was smeared around the doors of God's people in Egypt (Exodus 12:21-23). The threat of death was coming to every house in the country, but God said, "... when I see the blood I will pass over you" (Exodus 12:13). God commanded that a lamb could substitute for the life of the firstborn in every believing household; and then they would all be set free from slavery in Egypt.
