Acts 21:20-21

20 When they heard this, they praised God. Then they said to Paul, "Brother, you can see that many thousands of Jews have become believers. And they think it is very important to obey the law of Moses.

21 They have heard about your teaching, that you tell the Jews who live among those who are not Jews to leave the law of Moses. They have heard that you tell them not to circumcise their children and not to obey Jewish customs.
