The Blood on the Horns of the Altar of Incense

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. (Ver. 10.) The foundation is laid in atonement, and we know from Hebrews 10 that this yearly act was a type of the one offering of Jesus, whereby he hath perfected forever them that are sanctified.
And while no burnt sacrifice or meat offering was to be offered on this altar, yet the blood of atonement on the horns of it speaks of peace once made, and the remission of sins once for all through the sacrifice of Christ.
