Paul is comparing his death with the Old Testament ritual where wine or olive oil is poured on top of or beside the animal sacrifice that a worshiper would offer to God. What Paul means is that he would gladly die for the Philippians if that would make them more pleasing to God. AT: "But, even if the Romans decide to execute me, I will greatly rejoice if my death will make your faith and obedience more pleasing to God" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-activepassive]])
