Daniel 7:24-25

24As for the ten horns, out of this kingdom ten kings will arise; and another will arise after them, and he will be different from the former ones, and he will subdue three kings.

25He will speak words against the Most High [God] and wear down the saints of the Most High, and he will intend to change the times and the law; and they will be given into his hand for a time, [two] times, and half a time [three and one-half years].
