Daniel 12:6-7

6One of them spoke to the man who wore linen clothes and who now stood above the river. He asked that man, ‘How long will it be until these wonderful things finish?’

7The man who wore linen clothes lifted up both his hands towards the sky. I heard him make a strong promise with the authority of God, who lives for ever. He said, ‘It will continue for three and a half times. Then the enemies of God's holy people will finally lose their power. That will be the end of all these events.’
