Titus 1:10-13

For there are many rebellious people who engage in useless talk and deceive others. This is especially true of those who insist on circumcision for salvation. They must be silenced, because they are turning whole families away from the truth by their false teaching. And they do it only for money. Even one of their own men, a prophet from Crete, has said about them, “The people of Crete are all liars, cruel animals, and lazy gluttons.” This is true. So reprimand them sternly to make them strong in the faith.
