'Atonements' in the Bible

and a bullock, a sin-offering, thou dost prepare daily for the atonements, and thou hast atoned for the altar, in thy making atonement on it, and hast anointed it to sanctify it;

And Aaron shall make an atonement upon the horns of it once in a year with the blood of the sin offering of atonements: once in the year shall he make atonement upon it throughout your generations: it is most holy unto the LORD.
