'Feast' in the Bible

On the fifteenth day of this month shall be a feast, unleavened bread shall be eaten for seven days.

‘Also on the day of the first fruits, when you present a new grain offering to the Lord in your Feast of Weeks, you shall have a holy convocation; you shall do no laborious work.

‘Then on the fifteenth day of the seventh month you shall have a holy convocation; you shall do no laborious work, and you shall observe a feast to the Lord for seven days.
