Acts 21:21-24

21and 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. 22What is it therefore? they will certainly hear that thou art come. 23Do therefore this that we say to thee: We have four men that have a vow on them; 24these 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.
