Thomas Aquinas, on 1Tim 4:16

“Take heed to thyself and to doctrine: be earnest in them. For in doing this thou shalt both save thyself and them that hear thee.”

“These things he should do because of the reward he expects. Hence he adds, take heed to yourself and to doctrine. For some attend to doctrine so much that they neglect themselves; but the Apostle tells him to attend to himself first, and then to doctrine: have pity on your own soul (Sir 30:24). Hence Jesus began to do and to teach. Be earnest in them, i.e., do them insistently: be instant in season, out of season (2 Tim 4:2). The fruit will be abundant, for in doing this you shall save both yourself and those who hear you. And this is great: he who causes a sinner to be converted from the error of his way shall save his soul from death and shall cover a multitude of sins (Jas 5:20); they that instruct many to justice, as stars for all eternity (Dan 12:3). Hence teachers will receive a golden crown.”
