Festivals of the Jews, the three great annual: These were, the Feast of the Passover, that of Pentecost, and that of Tabernacles; on occasion of which, all the males of the nation were required to visit the temple at Jerusalem, in whatever part of the country they might reside. See Exodus 28:14, 17; 34:23; Leviticus 33: 4; Deuteronomy 16:16. The Passover was kept in commemoration of the deliverance of the Israelites from Egypt, and was so named because the night before their departure the destroying angel, who slew all the first-born of the Egyptians, passed over the houses of the Israelites without entering them. See Exodus 12. The Feast of Pentecost was so called from a word meaning the fiftieth, because it was celebrated on the fiftieth day after the Passover, and was instituted in commemoration of the giving of the Law from Mount Sinai on the fiftieth day from the departure out of Egypt. It is also called the Feast of Weeks, because it was kept seven weeks after the Passover. See Exodus 34:32; Leviticus 23: 15-21; Deuteronomy 16: 9, 10. The Feast of Tabernacles, or Feast of Tents, was so called because it was celebrated under tents or tabernacles of green boughs, and was designed to commemorate their dwelling in tents during their passage through the wilderness. At this feast they also returned thanks, to God for the fruits of the earth after they had been gathered. See Exodus 23: 16; Leviticus 33: 34-44; Deuteronomy 16:13; and also St. John 7: 2.
