Acts 21:17-26

17 When we had come to Yerushalayim, the brothers received us gladly.
18 The day following, Sha'ul went in with us to Ya`akov; and all the Zakenim were present.
19 When he had greeted them, he reported one by one the things which God had worked among the Goyim through his ministry.
20 They, when they heard it, glorified God. They said to him, "You see, brother, how many thousands there are among the Yehudim of those who have believed, and they are all zealous for the law.
21 They have been informed about you, that you teach all the Yehudim who are among the Goyim to forsake Moshe, telling them not to circumcise their children neither to walk after the customs.
22 What then? The assembly must certainly meet, for they will hear that you have come.
23 Therefore do what we tell you. We have four men who have a vow on them.
24 Take them, and purify yourself with them, and pay their expenses for them, that they may shave their heads. Then all will know that there is no truth in the things that they have been informed about you, but that you yourself also walk keeping the law.
25 But concerning the Goyim who believe, we have written our decision that they should observe no such thing, except that they should keep themselves from food offered to idols, from blood, from strangled things, and from sexual immorality."
26 Then Sha'ul took the men, and the next day, purified himself and went with them into the temple, declaring the fulfillment of the days of purification, until the offering was offered for every one of them.
