Pentecost
The fiftieth day — the annual holy day (a sabbath) that closes the Feast of Weeks, the culmination of its seven-week count. In Acts 2, the day the Spirit was poured out on the gathered ekklesia. The Greek pentēkostē simply means fiftieth. Pentecost is the holy day, not the feast itself — the feast is the seven weeks it completes. The connection between Pentecost and the eternal Jubilee cycle is explored in From Fifty Days to Eternity.
Synonyms: pentēkostē.
