The Feast of Tabernacles, known simply as "the Feast," was the most joyous celebration of the entire year for ancient Israel, following the harvest season after months of hard work. God commands rejoicing repeatedly in Leviticus 23, Deuteronomy 14, and Deuteronomy 16, where the instruction to rejoice appears three times, with a fourth emphatic declaration: "you shall surely rejoice." This rejoicing was never meant to be solitary but communal, shared among the entire community for all seven days.
