'Feast' in the Bible

The Lord has rejected His altar;He has abandoned His sanctuary.He has given into the hand of the enemyThe walls of her palaces;They have made a noise in the house of the LordAs on a day of an appointed feast.

You [Lord] called as in the day of an appointed feastMy terrors (dangers) on every side;And there was no one who escaped or survivedIn the day of the Lord’s anger.Those I have cared for and brought up with tenderness,My enemy annihilated them.
