Exodus 30:10

“And Aaron shall make an atonement upon the horns of it once in a year, etc.] On the day of atonement, as the Targum of Jonathan, and so Jarchi and Aben Ezra explain it; and the atonement here referred to seems to be an atonement for the altar itself, (see <031618>Leviticus 16:18,19) and as the altar of burnt offering was first expiated and then used, (<022936>Exodus 29:36,37) so it seems the altar of incense had not only an atonement made on it, but for it: and this was done with the blood of the sin offering of atonement; by sprinkling the blood of that offering upon the horns of it, as we learn from the afore mentioned place; and this shows that Christ’s mediation and intercession is…”
