Blood Moons? JEREMIAH 10:2

"Thus says the LORD, "Do not learn the way of the nations, And do not be terrified by the signs of the heavens Although the nations are terrified by them; For the customs of the peoples are delusion; JEREMIAH 10:2

Vs 2. - The way of the heathen. "Way" equivalent to "religion" (comp.  Acts 9:2, etc.). Be not dismayed at the signs of heaven; alluding to the astrological calculations based upon extraordinary appearances in the sky... confirmed by the Babylonian cuneiform tablets - that "the appearance of comets, eclipses of the sun and moon, earthquakes, and in fact every kind of change occasioned by the atmosphere, whether good or bad, both to nations and to kings and private individuals [were omens of future events]." 

More than likely the Sun darkened and the Moon turned as blood will be from the smoke and warfare described in Revelation. The merchants of the earth all will see the smoke of Mystery Babylon's destruction!  Prophesy describes Nuclear war...Zechariah 14:12
"And this shall be the plague wherewith Jehovah will smite all the peoples that have warred against Jerusalem: their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth."

The Man of Sin being revealed is the key...not signs and wonders!

1Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. 3Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 4Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. 5Remember ye not, that, when I was yet with you, I told you these things? 6And now ye know what withholdeth that he might be revealed in his time. 7For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. 8And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11And for this cause God shall send them strong delusion, that they should believe a lie: 12That they all might be damned who believed not the truth, but had pleasure in unrighteousness. 2 Thessalonians 2
