Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law.
Them take, and purify thyself with them. It will not follow from this (as some critics have too hastily concluded) that Paul himself was asked, and consented to take on him, the Nazarite vow. From the nature of that vow, which plainly contemplated some lengthened duration, it seems to us extremely unlikely that it would be thought of in the present case. All that seems meant here is, that Paul should so 'purify himself' ceremonially, as to be able to present himself as a cleansed man in, the temple on the completion of these four men's vow.
And be at charges with them, [dapaneeson (G1159) ep' ( G1909) autois (G846)] - 'pay expenses for them,' or defray the cost of the sacrifices legally required of them, along with his own; which was deemed a mark of Jewish generosity.
That they may shave their heads ( Numbers 6:9 ): and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law - not despising its ceremonial usages, but ready to comply with them.
