Because for his name's sake they went forth, taking nothing of the Gentiles.

For they have gone forth on
behalf of His name, viz, that they might preach the name of God and Christ, says Bede. Or else because for His name they have been driven into exile. The first of these is the more probable reason. And it is strengthened by what follows.
Taking nothing of the Gentiles. Because without price they preach the Gospel to the Gentiles, that they may not seem to gain any profit by the Gospel.
Taking nothing of the Gentiles. These ministers and preachers of the gospel, whom St. John recommends, took care, as St. Paul did, not to take any thing of the Gentiles, to whom they preached, lest they should be thought to preach to get money by it. But he puts Gaius in mind, that by assisting such men, he would become a fellow labourer in the gospel, and have a share in their reward. (Witham)
Taking nothing of the Gentiles: These ministers of the gospel are commended by St. John, who took nothing from the Gentiles, lest they should seem to preach in order to get money by it.
