Feast of Tabernacles, the name given in the Old Testament to a festival marking the close of the harvest in Palestine. As a harvest festival it is also known as the Feast of Ingathering (see Exodus 23:16, 34:22) and can be traced back to the Canaanites. It was given a historical aspect by adopting the Canaanite custom of dwelling in tabernacles, or booths, during the harvest and interpreting it as a reminder of the nomadic stage in the life of the Hebrew people, particularly of the 40 years' sojourn in the wilderness, when the tent was the only habitation—hence the festival's name Feast of Tabernacles (see Deuteronomy 16:13-16, 31:10-13; Leviticus 23:34-36, 39-44; Numbers 29:12-40).  (Source:  Microsoft Encarta Encyclopedia)
