Daniel 12:6-7

6And one said to the man dressed in linen, who was above the waters of the river, “How long will it be until the end of these wonders?”

7And I heard the man dressed in linen, who was above the waters of the river, as he held up his right hand and his left hand toward heaven, and swore by Him who lives forever that it would be for a time, times, and a half a time (three and a half years); and as soon as they finish shattering and crushing the power of the holy people, all these things will be finished.
