Daniel 12:7

And I heard the man clothed in linen, who was above the waters of the river, when he held up his right and his left hand toward the heavens and swore by Him Who lives forever that it shall be for a time, times, and a half a time [or three and one-half years]; and when they have made an end of shattering and crushing the power of the holy people, all these things shall be finished.
