Revelation 12:13-14

13And when the dragon saw that he was thrown down to the earth, he persecuted the woman who had given birth to the male Child.

14But the two wings of the great eagle were given to the woman, so that she could fly into the wilderness to her place, where she was nourished for a time and times and half a time (three and one-half years), away from the presence of the serpent (Satan).
