Acts 21:21-26

and they have been informed concerning thee, that thou teachest all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children, neither to walk after the customs. What is it therefore? they will certainly hear that thou art come. Do therefore this that we say to thee: We have four men that have a vow on them; these take, and purify thyself with them, and be at charges for them, that they may shave their heads: and all shall know that there is no truth in the things whereof they have been informed concerning thee; but that thou thyself also walkest orderly, keeping the law. But as touching the Gentiles that have believed, we wrote, giving judgment that they should keep themselves from things sacrificed to idols, and from blood, and from what is strangled, and from fornication. Then Paul took the men, and the next day purifying himself with them went into the temple, declaring the fulfilment of the days of purification, until the offering was offered for every one of them.
