From which some having swerved,.... The apostle, in this verse and the next, describes the persons he suspected of teaching other doctrines, and of introducing fables and endless genealogies; they were such who departed from the above things; they erred from the commandment, or law, notwithstanding their great pretensions to a regard unto it; at least they missed the mark, the end and design of it; they went astray from that, and instead of promoting charity or love, created feuds, contentions, and divisions in the churches; and were far from having a pure heart, being filthy dreamers, and sensual persons, destitute of the Spirit of God, and were such who put away a good conscience, and made shipwreck of faith: such were Hymenaeus, Philetus, Alexander, and others, of whom he also says, they
have turned aside to vain jangling; which he elsewhere calls empty talk, and vain babblings, 1 Timothy 6:20, from the solid doctrines of the Gospel, and a solid way of handling them, they turned to vain, idle, useless, and unprofitable subjects of discourse, and to treating upon subjects in a vain, jejune, and empty manner; entertaining their hearers with foolish and trifling questions and answers to them about the law, and with strifes about words, which were unserviceable and unedifying; they were unruly and vain talkers, Titus 1:10.
