{An offering and a sacrifice to God} (prosphoran kai thusian
t(9369) the(9369)). Accusative in apposition with heauton (himself).
Christ's death was an offering to God "in our behalf" (huper
h(886d)(936e)) not an offering to the devil (Anselm), a ransom
(lutron) as Christ himself said ( Mt 20:28 ), Christ's own view
of his atoning death. {For an odour of a sweet smell} (eis osm(886e)
eu(9364)ias). Same words in  Php 4:18  from  Le 4:31  (of the
expiatory offering). Paul often presents Christ's death as a
propitiation ( Ro 3:25 ) as in  1Jo 2:2 .
