Matthew Poole and continuators on Leviticus 16:18

18 And he shall go out unto the altar that is before the LORD, and make an atonement for it, and shall take of the blood of the bullock, and of the blood of the goat, and put it upon the horns of the altar round about.

To wit, the altar of incense, where the blood of sacrifices was to be put, Levit. 4. 4. and particularly the blood of the sin-offerings offered upon this day of atonement, Exod. 30. 10. and which is most truly and properly said to be before the Lord, i. e▪ before the place where God in special manner dwelt, to wit, the Holy of holies. Some understand it of the altar of burnt-offerings, because he is said to go out to it. But that going out relates not to the Tabernacle, but to the Holy of holie[illegible: 1+ letters] into which he was said to go in, ver. 17. Add to this, that this [illegible: 1 word] which is atoned by the High-priest seems to be in that place where he onely might now come, and therefore in the Holy place, called here the Tabernacle, from which all other priests were for this day excluded, whereas the altar of burntofferings was without the Holy place or Tabernacle, to wit at the door of it and in the court of the Priests.
