'Appointment' in the Bible

The Lord hath cast off His altar, He hath rejected His sanctuary, He hath shut up into the hand of the enemy The walls of her palaces, A noise they have made in the house of Jehovah Like a day of appointment.

Thou dost call as at a day of appointment, My fears from round about, And there hath not been in the day of the anger of Jehovah, An escaped and remaining one, They whom I stretched out and nourished, My enemy hath consumed!
