I know the next blood moon is coming up in 10/6 I think. Why is this 4 blood moon that's supposed to be some kind of sign not in bible. Maybe you guys can help me find it. I also want to know since we already had a blood moon in 4/15. Nothing happened. So is this blood moon a hoax. If not where is blood moon in bible. The one in the book of Joel and Matt. does not seem to be the same moon.
