John had earlier seen a beast with “blasphemous names” limited to “its heads” (Revelation 13:1). Now the names are plastered all over its body. The blasphemy implicit in this beast has become more pervasive, more in-your-face, more obviously all-encompassing of the beast’s nature. We are not told what these blasphemous names were, whether names of idols or pagan gods, or straight-out words slanderous of the Lord God. The fact that the woman rides this beast makes her responsible for its decorations, including its names. These names, then, are telling of her mindset. The woman is deep into anti-God messaging.
3 And he carried me away in the Spirit into a wilderness, and I saw a woman sitting on a scarlet beast that was full of blasphemous names, and it had seven heads and ten horns.
