2 Corinthians 11:13-15

New Revised Standard Version, Anglicised Catholic Edition

¹³ For such boasters are false apostles, deceitful workers, disguising themselves as apostles of Christ. ¹⁴ And no wonder! Even Satan disguises himself as an angel of light. ¹⁵ So it is not strange if his ministers also disguise themselves as ministers of righteousness. Their end will match their deeds.
