'Festival' in the Bible

Stop bringing useless offerings.Your incense is detestable to Me.New Moons and Sabbaths,and the calling of solemn assemblies—I cannot stand iniquity with a festival.

the festival robes, and the mantles, and the shawls, and the satchels;

On this mountain [Zion] the Lord of hosts will prepare a lavish banquet for all peoples [to welcome His reign on earth],A banquet of aged wines—choice pieces [flavored] with marrow,Of refined, aged wines.

Your singing will be like thaton the night of a holy festival,and your heart will rejoicelike one who walks to the music of a flute,going up to the mountain of the Lord,to the Rock of Israel.

Look at Zion, the city of our festival times.Your eyes will see Jerusalem,a peaceful pasture, a tent that does not wander;its tent pegs will not be pulled upnor will any of its cords be loosened.
