{And he} (kai autos). He himself in his own person, both
priest and sacrifice ( Heb 9:14 ). {The propitiation}
(hilasmos). Late substantive from hilaskomai ( Lu 18:13  Heb
2:17 ), in LXX, Philo, Plutarch, in N.T. only here and  4:10 .
Christ himself is the means of propitiation for (peri
concerning) our sins. See hilast(8872)ion in  Ro 3:15 . {For the
whole world} (peri holou tou kosmou). It is possible to supply
the ellipsis here of 	(936e) hamarti(936e) (the sins of) as we have it
in  Heb 7:27 , but a simpler way is just to regard "the whole
world" as a mass of sin ( 5:19 ). At any rate, the propitiation
by Christ provides for salvation for all ( Heb 2:9 ) if they will
only be reconciled with God ( 2Co 5:19-21 ).
