Exodus

Describes how Moses leads the Israelites out of Egypt and slavery, and how they receive laws from God.

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.

And Aaron shall make reconciliation vpon the hornes of it once in a yere with the blood of the sinne offring in the day of reconciliation: once in the yeere shall hee make reconciliation vpon it throughout your generations: this is most holy vnto the Lord.

Exodus 30:10
