Chapter 21, verses 21-24
21
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 neither to walk after the customs.
22
What then? The assembly must certainly meet, for they will hear that you have come.
23
Therefore do what we tell you. We have four men who have taken a vow.
24
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.
