2 Bible Verses about Red Moons

[In that day] the sun will become dark and the moon will [appear] as blood. [This will all happen] before the great and wonderful day when the Lord comes. [Note: Some view these last two verses as a reference to events occurring at the end of time. See Matt. 24:29-30].

Then I looked as the Lamb broke open the sixth seal, and there [I saw] a great earthquake; the sun turned as black as sackcloth made out of [goat] hair, and the entire moon turned [as red] as blood.
