Acts 21:20-21

20 But they hearing it, glorified God and said to him: Thou seest, brother, how many thousands there are among the Jews that have believed: and they are all zealous for the law.

21 Now they have heard of thee that thou teachest those Jews, who are among the Gentiles to depart from Moses: saying that they ought not to circumcise their children, nor walk according to the custom.
