The final plague against Egypt was a dramatic and devastating judgement by God. The people of Israel are instructed to make public their faith in God through the costly sacrifice of a spotless lamb. Through this the Lord makes clear that He deserves the best - not the extras - in the worship of His people. And God also foreshadows the coming of True Salvation through the sacrifice of the Lamb of God, Jesus Christ, which is the only means of deliverance from sin and the price of death.
