Daniel 8:13-14

13Then I heard two angels as they talked to each other. One angel asked, ‘How long will the things in this vision continue to happen? How long will this disgusting thing stop the sacrifices each day? How long will it stand against God and stamp on his temple and his army?’

14The other angel answered, ‘It will continue for 2,300 evenings and mornings. After that, God's temple will be clean again.’
