2:31 The sunlight will be turned to darkness
and the moon to the color of blood, 1
before the day of the Lord comes –
that great and terrible day!
1 tn Heb “to blood,” but no doubt this is intended to indicate by metonymy the color of blood rather than the substance itself. The blood red color suggests a visual impression here – something that could be caused by fires, volcanic dust, sandstorms, or other atmospheric phenomena.
