🧐 Hmmm?
Wiki is the source:
The claim of a blood moon being a sign of the beginning of the end times originates in the Book of Joel, where it is written "the sun will turn into darkness, and the moon into blood, before the great and terrible day of the Lord comes."[4] This prophecy repeated by Peter during Pentecost, as stated in Acts,[5] though Peter says that the date of Pentecost, not a future date, was the fulfillment of Joel's prophecy. The blood moon also is prophesied in the Book of Revelation chapter 6 verses 11–13,[6] where verse 12 states, "And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood."
