2 Peter 2:3

2:3 And in their greed they will exploit you with deceptive words. Their condemnation pronounced long ago is not sitting idly by; their destruction is not asleep.

Galatians 2:4

2:4 Now this matter arose because of the false brothers with false pretenses who slipped in unnoticed to spy on our freedom that we have in Christ Jesus, to make us slaves.
