Acts 21:21-26

²¹and they have been told about you, that you are teaching all the Jews who are among the Gentiles to abandon Moses, telling them not to circumcise their children nor to walk according to the customs. ²²So what is to be done? They will certainly hear that you have come. ²³Therefore, do as we tell you: we have four men who have a vow upon themselves; ²⁴take them along and purify yourself together with them, and pay their expenses so that they may shave their heads; and then everyone will know that there is nothing to what they have been told about you, but that you yourself also conform, keeping the Law. ²⁵But regarding the Gentiles who have believed, we sent a letter, having decided that they should abstain from meat sacrificed to idols and from blood and what is strangled, and from sexual immorality.” ²⁶Then Paul took along the men, and the next day, after purifying himself together with them, he went into the temple giving notice of the completion of the days of purification, until the sacrifice was offered for each one of them.
