2 Corinthians 11:13-15 English Standard Version (ESV)
13 For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ.
14 And no wonder, for even
Satan disguises himself as an angel of light.
15 So it is no surprise if his servants, also, disguise themselves as servants of righteousness. Their end will correspond to their deeds.
