²⁹ For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.

¹⁷ Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.

¹⁸ For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.

¹² But what I do, that I will do, that I may cut off occasion from them which desire occasion; that wherein they glory, they may be found even as we.

¹³ For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.

¹⁴ And no marvel; for Satan himself is transformed into an angel of light.
