The 3 1/2 years is a term coming from bible commentators, who have made a mistake in not realizing that the 42 months, and the time/times/half are not "exact" equivalents to 3 1/2 years or the 1260 days.
The terms in Revelation and Daniel are the time/times/half time ; the 1260 days; the 42 months; the 3 1/2 days; the 2300 days; the one week (Daniel 9:27).
_______________________________________________________
Regarding the 1260 days in Revelation 12:6 is the first half of the 7 years in Revelation 12.
Mary is not the woman in the first five verses of Revelation 12. The woman represents Israel. Unto us a child is born.
Isaiah 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
The woman thus in Revelation 12:6 and the rest of Revelation 12 is Israel.
Who is the woman in the passage below?
Rev 12:5
And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.
Based on the genealogies in the New Testament, can Mary be separated from Israel?
