But speak thou - In thine own ministry. In the previous chapter he had given him instructions as to the kind of persons who were to be put into the sacred office. Here he gives him special instructions in regard to his own preaching. "The things which become sound doctrine." To wit, those which he proceeds immediately to specify. On the phrase sound doctrine, see the notes at 1 Timothy 1:10; compare 2 Timothy 4:3.

But speak thou the things - This is a conclusion drawn from the preceding chapter: the Judaizing teachers not only taught a false doctrine, but they led an unholy life; Titus was to act directly opposite; he must teach a sacred doctrine, and the things which become it; he must proclaim the truth, and illustrate that truth. The people must not only be well instructed, but they must be holy in their lives. Principle and practice must go hand in hand.

But speak thou the things which become sound doctrine. Concerning sound doctrine, and the form of it; see Gill on 2 Timothy 1:13. The things which become it are a good life and conversation, the various duties incumbent on professors of religion, according to their different station, age, and sex, which are observed in some following verses; these become the Gospel of Christ, and are ornamental to the doctrine of God our Saviour; and these are to be spoken of by the ministers of Christ, in their proper places, and at proper times; who ought not to be dumb, and keep silence at any time, but especially when there are many unruly and vain talkers: sound doctrine ought to be spoken out openly and publicly, fully and faithfully, with great plainness and evidence, that it may be understood and known by all; and with much certainty, without hesitation, as being, without controversy, undoubted truth; and with all boldness, not fearing men, or seeking to please them; and it should be constantly and continually spoken, in season, and out of season; and care should be taken that it be spoken consistently, and in an uniform manner, that there be no clashing and contradiction; and the duties of religion, which become sound doctrine, should be set in their true light, and proper place, as fruits of the grace of God, and to glorify him; these should be spoken out plainly, frequently insisted upon, and warmly and zealously urged, as being decent things, for the honour of God, the recommending of religion, the good of mankind, and the service of one another: as particularly,

Speak thou (λάλει)

See on Matthew 28:18; see on John 8:26.

Become (πρέπει)

Originally, to stand out; be conspicuous. Thus Homer, Od. viii. 172: μετὰ δὲ πρέπει ἀγρομένοισιν he is conspicuous among those who are assembled. Eurip. Hel. 215; Ζεὺς πρέπων δἰ αἰθερος Zeus shining clearly through the aether. Hence, to become conspicuously fit; to become; beseem. In N.T. in the impersonal forms πρέπον ἐστὶν it is becoming (Matthew 3:15); πρέπει it becometh (Ephesians 5:3); ἔπρεπεν it became (Hebrews 2:10). With a subject nominative, 1 Timothy 2:10; Hebrews 7:26.

But {1} speak thou the things which become sound doctrine:

(1) The fifth admonition: the doctrine must not only be generally pure, but also be applied to all ages and orders of men, according to the diversity of circumstances.

CHAPTER 2

Tit 2:1-15. Directions to Titus: How to Exhort Various Classes of Believers: The Grace of God in Christ Our Grand Incentive to Live Godly.

1. But . thou-in contrast to the reprobate seducers stigmatized in Tit 1:11, 15, 16. "He deals more in exhortations, because those intent on useless questions needed chiefly to be recalled to the study of a holy, moral life; for nothing so effectually allays men's wandering curiosity, as the being brought to recognize those duties in which they ought to exercise themselves" [Calvin].

speak-without restraint: contrast Tit 1:11, "mouths . stopped."

doctrine-"instruction" or "teaching."

2:1-8 Old disciples of Christ must behave in every thing agreeably to the Christian doctrine. That the aged men be sober; not thinking that the decays of nature will justify any excess; but seeking comfort from nearer communion with God, not from any undue indulgence. Faith works by, and must be seen in love, of God for himself, and of men for God's sake. Aged persons are apt to be peevish and fretful; therefore need to be on their guard. Though there is not express Scripture for every word, or look, yet there are general rules, according to which all must be ordered. Young women must be sober and discreet; for many expose themselves to fatal temptations by what at first might be only want of discretion. The reason is added, that the word of God may not be blasphemed. Failures in duties greatly reproach Christianity. Young men are apt to be eager and thoughtless, therefore must be earnestly called upon to be sober-minded: there are more young people ruined by pride than by any other sin. Every godly man's endeavour must be to stop the mouths of adversaries. Let thine own conscience answer for thine uprightness. What a glory is it for a Christian, when that mouth which would fain open itself against him, cannot find any evil in him to speak of!
