Exodus 30:10

And once in the year Aaron shall make atonement on its horns, he shall purge it with the blood of purification for their generations: it is most holy to the Lord.

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.

Aaron shall make atonement on its horns once in the year; with the blood of the sin offering of atonement once in the year he shall make atonement for it throughout your generations. It is most holy to Yahweh.”
