Acts 21:20-21

20 And they, when they heard it, glorified God; and they said unto him, Thou seest, brother, how many thousands there are among the Jews of them that have believed; and they are all zealous for the law:

21 and they have been informed concerning thee, that thou teachest all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children neither to walk after the customs.
