2 Corinthians 11:14

And no marvel; for Satan himself is transformed into an angel of light.

Ver. 14. Satan himself is, &c.] Satan, saith one, doth not always appear in one and the same fashion, but hath as many different changes as Proteus among the poets. At Lystra he appears like a comedian, as if a scene of Plutus were to be presented on the stage. At Antioch like a Jesuit, with traditions in his mouth. At Athens he sallies out like a philosopher; at Ephesus like a craftsman; and here at Corinth he is transformed into an angel of light. Fiery serpents full of deadly poison are called seraphims, Numbers 21:6; Isaiah 30:6 .
