15-21. Feast of Weeks. Fifty days or seven weeks after the last festival, the Feast of Weeks, called in Gk. 'Pentecost' from the word for 'fifty,' began with the presentation of two loaves made of the new wheat and leavened in the ordinary way, signifying that harvest was completed. Hence this feast, which lasted only a single day, is called also the Feast of Harvest in Exodus 23:16. For the sacrifices offered see Leviticus 23:18 Numbers 28:26.
