'Festival' in the Bible

So all the men of Israel were assembled in the presence of King Solomon in the seventh month, the month of Ethanim, at the festival.

Solomon and all Israel with him—a great assembly, from the entrance of Hamath to the Brook of Egypt—observed the festival at that time in the presence of the Lord our God, seven days, and seven more days—14 days.

On the fifteenth day after the festival started, he dismissed the people. They asked God to empower the king and then went to their homes, happy and content because of all the good the Lord had done for his servant David and his people Israel.

Jeroboam made a festival in the eighth month on the fifteenth day of the month, like the festival in Judah. He offered sacrifices on the altar; he made this offering in Bethel to sacrifice to the calves he had set up. He also stationed the priests in Bethel for the high places he had set up.

He offered sacrifices on the altar he had set up in Bethel on the fifteenth day of the eighth month. He chose this month on his own. He made a festival for the Israelites, offered sacrifices on the altar, and burned incense.
