Hebrews 9:12

9:12 and he entered once for all into the most holy place not by the blood of goats and calves but by his own blood, and so he himself secured ¹  eternal redemption.

Hebrews 7:27

7:27 He has no need to do every day what those priests do, to offer sacrifices first for their own sins and then for the sins of the people, since he did this in offering himself once for all.

[9:12]  ¹ tn This verb occurs in the Greek middle voice, which here intensifies the role of the subject, Christ, in accomplishing the action: “he alone secured”; “he and no other secured.”
