Revelation 13:5-7

5And he was given a mouth speaking great things and blasphemies, and he was given authority to continue for forty-two months.

6Then he opened his mouth in blasphemy against God, to blaspheme His name, His tabernacle, and those who dwell in heaven.

7It was granted to him to make war with the saints and to overcome them. And authority was given him over every tribe, tongue, and nation.
