A prominent Israelite festival was the Feast of Tabernacles, sometimes referred to as the feast of tents or the Feast of Booths. At that festival, everyone would come with their families. This was different than the men going to get the sacrifice for the Passover. At Tabernacles, the entire family would come, and their men, women, and children would sit in a booth—a sukkah—that had been created to remind them that their ancestors had dwelt in tents as they wandered in the wilderness for forty years. These tents have significance. At the Feast of Tabernacles, once every seven years, the law was read, and the people renewed their covenant to keep the Law of Moses.
