Acts 21:23-26

23Therefore do what we tell you: We have four men who have made a vow.

24Take these men, purify yourself along with them, and pay for them to get their heads shaved. Then everyone will know that what they were told about you amounts to nothing, but that you yourself are also careful about observing the law.

25With regard to the Gentiles who have believed, we have written a letter containing our decision that they should keep themselves from food sacrificed to idols, from blood, from what is strangled, and from sexual immorality.”

26So the next day, Paul took the men, having purified himself along with them, and entered the temple, announcing the completion of the purification days when the offering would be made for each of them.
