Galatians 5:8-10

Amplified Bible

⁸ This [deceptive] persuasion is not from Him who called you [to freedom in Christ]. ⁹ A little ^[a]leaven [a slight inclination to error, or a few false teachers] leavens the whole batch [it perverts the concept of faith and misleads the church]. ¹⁰ I have confidence in you in the Lord that you will adopt no other view [contrary to mine on the matter]; but the one who is disturbing you, whoever he is, will have to bear the penalty.
