What does the Bible say about the Passover in Exodus 12?

Exodus 12 outlines the critical event of the Passover, where God instructed the Israelites to take a lamb without blemish and to smear its blood on their doorposts. This act was not merely a protective measure but a divine symbol of God's covenant with His people. When the Lord passed through Egypt to strike down the firstborn of each household, He promised to spare those marked by the blood, which signifies the essential role of atonement in God's salvation plan. This event not only delivers Israel from Egyptian bondage but also serves as a foreshadowing of Christ's sacrifice, highlighting the necessity of personal faith and the acknowledgment of one's sinner status.
