Acts 21:22

When he had greeted them, he reported one by one the things which God had worked among the Gentiles through his ministry.

They, when they heard it, glorified God. They said to him, “You see, brother, how many thousands there are among the Jews of those who have believed, and they are all zealous for the law.

They have been informed about you, that you teach all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children and not to walk after the customs.

Therefore do what we tell you. We have four men who have taken a vow.

Take them and purify yourself with them, and pay their expenses for them, that they may shave their heads. Then all will know that there is no truth in the things that they have been informed about you, but that you yourself also walk keeping the law.

But concerning the Gentiles who believe, we have written our decision that they should observe no such thing, except that they should keep themselves from food offered to idols, from blood, from strangled things, and from sexual immorality.”
