John 7:2 - Ellicott's Commentary On The Whole Bible

The Jews’ feast of tabernacles. — This began on “the fifteenth day of the seventh month” (Leviticus 23:34), i.e., the 15th of Tishri, which answers to our September. The interval, then, from Passover to Tabernacles is one of about five months. The feast continued for seven days, during which all true Israelites dwelt in booths, in remembrance of their dwelling in tabernacles when they came out of the land of Egypt. Like the Feast of Unleavened Bread (Passover) and the Feast of Harvest (Pentecost), this Feast of In-gathering was one of the “three times in the year” when every male Jew was required to appear before the Lord God (Exodus 23:14). Josephus speaks of it as the holiest and greatest of the feasts. It was at once a thankful memorial of the national deliverance, and a yearly rejoicing at the close of each succeeding harvest (Deuteronomy 16:13-16).
