{When he had offered} (prosenegkas). Second aorist active
participle (with first aorist ending -as in place of -on) of
prospher(935c), single act in contrast to present participle
prospher(936e) above. {One sacrifice} (mian thusian). This the
main point. The one sacrifice does the work that the many failed
to do. One wonders how priests who claim that the "mass" is the
sacrifice of Christ's body repeated explain this verse. {For
ever} (eis to di(886e)ekes). Can be construed either with mian
thusian or with ekathisen (sat down). See  1:3  for
ekathisen.
