{Else must he often have suffered} (epei edei auton
pollakis pathein). A common elliptical use of epei after which
one must supply "if that were true" or "in that case," a protasis
of a condition of the second class assumed to be untrue. The
conclusion with edei is without an (verbs of necessity,
obligation, etc.). See Robertson, _Grammar_, p. 963. The
conclusion with an occurs in  10:2 . See also  1Co 5:10 .
"Since, if that were true, it would be necessary for him to
suffer often." {Since the foundation of the world} (apo
katabol(8873) kosmou). See  4:3  for this phrase. The one sacrifice
of Christ is of absolute and final value ( 1Pe 1:19f.  Re 13:8 ).
{At the end} (epi suntelei(8369)). Consummation or completion as in
 Mt 13:39f.  which see. {Hath he been manifested}
(pephaner(9374)ai). Perfect passive indicative of phanero(935c),
permanent state. See "the primitive hymn or confession of faith"
(Moffatt) in  1Ti 3:16  and also  1Pe 1:20 . Jesus came once for
all ( Heb 1:2 ). {To put away sin} (eis athet(8873)in t(8873)
hamartias). See  7:18  for the word athet(8873)is. "The sacrifice
of Christ dealt with sin as a principle: the Levitical sacrifices
with individual transgressions" (Vincent).
