This was the day when the people of Israel were washed from their sins. On this day, in order to wash away the sins of the people of Israel, the high priest had to first offer a sacrifice for himself and his household. This was necessary because the high priest could only fulfill his priestly duty and blot out the sins of the people of Israel if he himself was washed clean from his sins. Through the Day of Atonement, God not only blotted out the sins of the Israelites, but He also promised the special gift of salvation to the entire human race.
