Dearly beloved, thou dost faithfully whatever thou dost for the brethren, and that for strangers,

“Beloved, thou doest faithfully,.... Or a faithful thing, and as became a faithful man, a believer in Christ; in all his beneficence and charity he acted the upright part; he did not do it in an hypocritical way, to be seen of men, and gain applause from them, but from a principle of love, and with a view to the glory of God: whatsoever thou doest to the brethren, and to strangers; which may design either different persons; and by "brethren" may be meant the poor brethren of the church that. Gaius belonged to, and others that were well known to him; and by "the strangers", not unconverted persons, but such of the saints as came from foreign parts, and travelled about to spread the Gospel, and enlarge the interest of Christ: or else the same persons may be intended, for the words may be read, as they are in the Alexandrian copy, and some others, and in the Vulgate Latin version, "what thou doest to the brethren, and this to strangers"; that is, as the Arabic version renders it, "to strange brethren"; or, as the Syriac version, "to the brethren, and especially them that are strangers"; so that Gaius was a very hospitable man, one that entertained and lodged strangers, and used them very civilly and courteously, with great liberality, and with much integrity and sincerity.”

“faithfully--an act becoming a faithful man. whatsoever thou doest--a distinct Greek word from the former "doest": translate, "workest": whatsoever work, or labor of love, thou dost perform. So Mat 26:10, "She hath wrought a good work upon me." and to strangers--The oldest manuscripts, "and that (that is, and those brethren) strangers." The fact of the brethren whom thou didst entertain being "strangers," enhances the love manifested in the act.”
