Acts 21:20-21 RSV

20 And when they heard it, they glorified God. And they said to him, "You see, brother, how many thousands there are among the Jews of those who have believed; they are all zealous for the law,
21 and they have been told about you that you teach all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children or observe the customs.
