Hebrews 10:2 imagines the end of sacrifices if cleansed; 10:18 confirms that forgiveness has made them obsolete.

Hebrews 10:14 states Christ's sacrifice perfects forever; 10:18 concludes no further offering is needed — a direct logical link.

Jeremiah 31:34 is the OT prophecy of complete forgiveness that underlies the argument in 10:17-18.

Ephesians 1:7 describes redemption and forgiveness through Christ's blood — the same reality that makes sacrifice unnecessary in 10:18.
