Acts 21:21-25

21But they are under the impression that you teach all the Jews who live among the Gentiles to forsake Moses, telling them not to circumcise their children or observe our customs. 22What then should we do? They will certainly hear that you have come.

23Therefore do what we advise you. There are four men with us who have taken a vow. 24Take these men, purify yourself along with them, and pay their expenses so they can have their heads shaved. Then everyone will know that there is no truth to these rumors about you, but that you also live in obedience to the law.

25As for the Gentile believers, we have written to them our decision that they must abstain from food sacrificed to idols, from blood, from the meat of strangled animals, and from sexual immorality.”
