2 Corinthians 11:13-15

Revised Standard Version Catholic Edition

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 not strange if his servants also disguise themselves as servants of righteousness. Their end will correspond to their deeds.
