'Festival' in the Bible

ז ZayinThe Lord has rejected His altar,repudiated His sanctuary;He has handed the walls of her palacesover to the enemy.They have raised a shout in the house of the Lordas on the day of an appointed festival.

ת TavYou summoned my attackers on every side,as if for an appointed festival day;on the day of the Lord’s angerno one escaped or survived.My enemy has destroyedthose I nurtured and reared.
