The first goat is a blood sacrifice to cleanse the altar. The second goat—the 'azazel' or 'complete removal'—is led away and freed (not bound by a chain).
Some say the scapegoat (azazel) prefigures the Devil, others say it has been fulfilled by Jesus. Tradition teaches one thing; Scripture reveals another.
While the church of God has long taught that the azazel goat of Leviticus 16 represents Satan, this traditional view has no biblical support.
On the Day of Atonement, the live goat bears the sins of the nation. Many think this represents Satan as the source of sin, yet Scripture reveals the truth.
The Day of Atonement is not about Satan, but about the complete cleansing from sins through Christ. The Passover is not a sin offering, but a peace offering.
The goat for azazel (complete removal) bore the sins of the nation out of sight. Jesus Christ likewise had our iniquities laid on Him, and He bore them.
Hebrews 9 and 10 clarify the Atonement ritual of Leviticus 16. The author makes no mention of Satan, but says that Jesus bears our sins like the azazel goat.
Some modern translations of Leviticus 16 assert that the live goat (scapegoat) was a sacrifice that God commanded Israel to send to a demon named Azazel!
The Day of Atonement represents both a blood sacrifice for covering/cleansing and a means of removing sin permanently from the camp of Israel.
God employs a winnowing process in selecting those who will enter the Millennium. The process includes punishment for Israel's failure to serve as priests.
We cannot assume that angels are immortal and share the same kind of spirit God Almighty has; we cannot assume they are indestructible.
