Acts 21:20-26
20But they hearing it, glorified God, and said to him: Thou seest, brother, how many thousands there are among the Jews that have believed: and they are all zealous for the law.
21Now they have heard of thee that thou teachest those Jews, who are among the Gentiles, to depart from Moses: saying, that they ought not to circumcise their children, nor walk according to the custom.
22What is it therefore? the multitude must needs come together: for they will hear that thou art come.
23Do therefore this that we say to thee. We have four men, who have a vow on them.
24Take these, and sanctify thyself with them: and bestow on them, that they may shave their heads: and all will know that the things which they have heard of thee, are false; but that thou thyself also walkest keeping the law.
25But as touching the Gentiles that believe, we have written, decreeing that they should only refrain themselves from that which has been offered to idols, and from blood, and from things strangles, and from fornication.
26Then Paul took the men, and the next day being purified with them, entered into the temple, giving notice of the accomplishment of the days of purification, until an oblation should be offered for every one of them.
