Acts 21:23-26

23This do therefore that we say to thee: We have four men who have a vow on them;

24take these and be purified with them, and pay their expenses, that they may have their heads shaved; and all will know that [of those things] of which they have been informed about thee nothing is [true]; but that thou thyself also walkest orderly, keeping the law.

25But concerning [those of] the nations who have believed, we have written, deciding that they should [observe no such thing, only to] keep themselves both from things offered to idols, and from blood, and from things strangled, and from fornication.

26Then Paul, taking the men, on the next day, having been purified, entered with them into the temple, signifying the time the days of the purification would be fulfilled, until the offering was offered for every one of them.
