We have in fact the blood on the mercy-seat, and the scapegoat, in Rom. 3; 4 Only the Lord's lot is set out in testimony for us as guilty to come, an ιλαστήριον (mercy-seat) through faith in His blood. The scape-goat is as delivered for our offenses (if not raised again for our justification). And propitiation, though in view of God's glory (“among whom I dwell”), still is for sins, as 1 John 2 The Lord's lot was a sin-offering, but in general for God Who was there.
