Blasphemy, the vilification of heaven

Revelation 13 ⁶And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.⁷And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
Daniel 8:10 And it waxed great, even to the host of heaven; and it cast down some of the host and of the stars to the ground, and stamped upon them. 11 Yea, he magnified himself even to the prince of the host, and by him the daily sacrifice was taken away, and the place of his sanctuary was cast down. 12 And an host was given him against the daily sacrifice by reason of transgression, and it cast down the truth to the ground; and it practiced, and prospered.
