'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.

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.
