Leviticus 16:18

And he shall go out unto the altar that is before the Lord The Mishna sees here a reference to the golden altar (Yoma, 58 b), but this must be questioned: throughout this chapter -the altar" is mentioned, and in Leviticus 16:12, where it undoubtedly means the altar of Burnt-Offering, it is described as -the altar before the Lord," as in this verse. The words -and he shall go out," after the purification of the whole tabernacle enjoined in Leviticus 16:16, can hardly have any other meaning than -he shall go out of the tabernacle into the court in which was the brasen altar." In Exodus 30:10 the high priest is commanded to make atonement for the altar of incense once a year with the blood of the Sin-Offering of atonement, but the performance of this rite is not recorded here.
