Luke
Acts 21:24BSB·traditional attribution

Take these men, purify yourself along with them, and pay their expenses so they can have their heads shaved. Then everyone will know that there is no truth to these rumors about you, but that you also live in obedience to the law.

John Calvin Reformed @genevareformer

24. Which they have heard of thee are nothing. They seem to persuade Paul to dissemble. For the rumor rose not upon nothing, that he did call away the Jews from the ceremonies, and that he did not walk in observing the law.

Matthew Henry Presbyterian @wholebiblehenry

In these verses we have, I. Paul's journey to Jerusalem from Caesarea, and the company that went along with him. 1. They took up their carriages, their bag and baggage, and as it should seem, like poor travellers or soldiers, were their own porters; so little had they of change of raiment. Omnia mea mecum porto - My property is all about me.

John Gill Reformed Baptist @doctorgill

Them take, and purify, thyself with them,.... That is, join thyself to them, make one of their number, and attend to the rules prescribed to a Nazarite, who is to be holy to the Lord; and in case of any ceremonial uncleanness, is to be cleansed, or purified in the manner directed, Num 6:5.
