Acts 21:20-21

20 And when they heard it, they glorified the Lord and said unto him, "Thou seest, brother, how many thousands of Jews there are who believe, and they are all zealous for the law.

21 And they are informed about thee, that thou teachest all the Jews who are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, nor walk according to the customs.
