Acts 21:20-21

20 And [when] they heard [this], they began to glorify God. And they said to him, "You see, brother, how many ten thousands there are among the Jews who have believed, and they are all zealous adherents of the law.
21 And they have been informed about you that you are teaching all the Jews [who are] among the Gentiles [the] abandonment of Moses, telling them not to circumcise [their] children or to live according to [our] customs.
