Acts 21:20-21

20 And when they heard [it], they glorified the Lord, and said to him, Thou seest, brother, how many thousands of Jews there are who believe; and they are all zealous of the law:

21 And they are informed concerning thee, that thou teachest all the Jews who are among the Gentiles to forsake Moses, saying, That they ought not to circumcise [their] children, neither to walk after the customs.
