1911 Encyclopædia Britannica/Pentecost (1911)
“ We have further precise details respecting the sin-offering and the peace-offerings which were also presented. [1] This elaborate ceremonial connected with the wave-offering (developed in the post-exile period) took place on the morrow of the seventh Sabbath called a “day of holy convocation” on which no servile work was to be done. It was called a “fiftieth-day feast.” Pentecost or “Fiftieth” day is only a Greek equivalent of the last name (πεντηκοστή) in the Apocrypha and New Testament. ”
