John 7:2

Feast of tabernacles] or, 'feast of ingathering,' or, 'of harvest,' held in October, marked the completion of the harvest of fruit, oil, and wine. For eight days the people lived in booths, in memory of the wanderings in the wilderness. Numerous sacrifices were offered. Among the notable ceremonies were the procession to Siloam to fetch water, and its pouring out at the altar (cp. John 7:37), the singing of the Hallel (Psalms 113-118), the daily processions round the altar, and the lighting of the four great golden candlesticks in the Court of the Women (cp. John 8:12).
