'Festival' in the Bible

"Tell the Israelis that these are my festival times appointed by the LORD that you are to declare as sacred assemblies:

The Festival of Unleavened Bread to the Lord is on the fifteenth day of the same month. For seven days you must eat unleavened bread.

“Tell the Israelites: The Festival of Booths to the Lord begins on the fifteenth day of this seventh month and continues for seven days.

“You are to celebrate the Lord’s festival on the fifteenth day of the seventh month for seven days after you have gathered the produce of the land. There will be complete rest on the first day and complete rest on the eighth day.

You are to celebrate it as a festival to the Lord seven days each year. This is a permanent statute for you throughout your generations; you must celebrate it in the seventh month.
