Revelation 3:4 - Joseph Benson’s Commentary on the Old and New Testaments

Yet thou hast a few names That is, persons; even in Sardis Corrupt and indolent as the general state of the place is; who have not defiled their garments Who, notwithstanding the common corruption, have preserved their purity, having neither spotted themselves, nor partaken of the guilt of other men's sins. These persons, though few, had not separated themselves from the rest; otherwise the angel of this church would not have had them. Yet it was no virtue of his that they were unspotted; whereas it was his fault that they were but few. They shall walk with me in white In joy, in perfect holiness, in glory. “It is well known that white robes were worn on occasions of great joy, and sometimes in triumphal processions; to both which there is probably a reference here. Priests also were clothed in white; and the addition of that dignity may likewise be implied as certainly coming within the scheme of Christ with regard to his people: see Revelation 1:6. Some think here is an allusion to the custom of the sanhedrim, when they examined the candidates for the high-priesthood; if they judged the candidate worthy, they gave him a white garment; if unqualified, he was sent out from among them in mourning.” Doddridge. For they are worthy A few good among many bad are doubly acceptable unto God. O how much happier is this worthiness than that mentioned Revelation 16:6.
