It is the last day of the High Holy Days and the last day of teshuva (a 40 day period when people repent for sin). The word atonement means "to cover". On the Day of Atonement, the sins of the Jewish nation were covered by the blood of the sacrifice. The procedure is detailed in Leviticus 16. On this day the High Priest entered the Holy of Holies four times and he:

  1. burned incense
  2. sprinkles bull blood
  3. sprinkles goats blood
  4. he would retrieve the golden incense ladle

This is the only day in the Bible that required a day of fasting (Leviticus 23: 27,32; Jeremiah 36:6). Jesus fulfilled the Day of Atonement when He went into the heavenly Holy of Holies with his own blood and He fulfilled it with his own blood for the sins of the world. On this day:

  1. The High Preist on this day would dress in white then place his hands on the face of a bull and confess his sins before the congregation 
  2. They slaughtered the bull, put the blood into a golden bowl and then sprinkled it on the mercy seat.
  3. Next, he drew lots for 2 identical goats Lev 16:18
    1. One goat received the lot for the sacrifice
    2. The other was a scapegoat for Azazel
      1. The scapegoat: the high priest would lay his hands on the goats head and confessed the sins of the nation then he would turn to the people and exclaim "You shall be clean!". At that point, the goat would be taken out of the city and released never to be seen again. 
      2. Rabbis say that Azazel is the place where the Almighty banishes sin. The book of Enoch says that Azazel is the name of an evil spirit.
  4. The goat they received for the sacrifice they slaughtered it then sprinkled the mercy seat with the goat's blood. 
  5. According to the Talmud, there was a scarlet cord tied to the door of the temple and as the scapegoat ran away the cord would turn white. This was a sign that the God had removed Israel's guilt.

We receive forgiveness and Sozo (being saved, healed, delivered) when we change our minds, perceptions, and attitudes aka repent. When we do this we a purified before God so that we can have continual fellowship with him. 

1 John 1:6-9

If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:

But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

If we say that we have no sin, we deceive ourselves, and the truth is not in us.

If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
