I Timothy 4:12

Let no man despise thy youth - Act with all the gravity and decorum which become thy situation in the Church. As thou art in the place of an elder, act as an elder. Boyish playfulness ill becomes a minister of the Gospel, whatever his age may be. Concerning Timothy's age see the conclusion of the preface to this epistle. Be thou an example of the believers - It is natural for the flock to follow the shepherd; if he go wrong, they will go wrong also. "Himself a wanderer from the narrow way, His silly sheep, no wonder if they stray." Though, according to the just judgement of God, they who die in their sins have their blood on their own head; yet, if they have either gone into sin or continued in it through the watchman's fault, their blood will God require at his hand. How many have endeavored to excuse their transgressions by alleging, in vindication of their conduct, "Our minister does so, and he is more wise and learned than we." What an awful account must such have to give to the Head of the Church when he appears! In word - Εν λογῳ· In doctrine; teach nothing but the truth of God, because nothing but that will save souls. In conversation - Εν αναστροφῃ· In the whole of thy conduct in every department which thou fillest in all thy domestic as well as public relations, behave thyself well. In charity - Εν αγαπῃ· In love to God and man; show that this is the principle and motive of all thy conduct. In spirit - Εν πνευματι· In the manner and disposition in which thou dost all things. How often is a holy or charitable work done in an unholy, uncharitable, and peevish spirit! To the doer, such work is unfruitful. These words are wanting in ACDFG, and several others; both the Syriac, Erpen's Arabic, Ethiopic, Armenian, Vulgate, and Itala, and many of the fathers. Griesb…

Let no man despise thy youth--Act so as to be respected in spite of thy youth (Co1 16:11; Tit 2:15); compare "youthful" as to Timothy (Ti2 2:22). He was but a mere youth when he joined Paul (Act 16:1-3). Eleven years had elapsed since then to the time subsequent to Paul's first imprisonment. He was, therefore, still young; especially in comparison with Paul, whose place he was filling; also in relation to elderly presbyters whom he should "entreat as a father" (Ti1 5:1), and generally in respect to his duties in rebuking, exhorting, and ordaining (Ti1 3:1), which ordinarily accord best with an elderly person (Ti1 5:19). be thou an example--Greek, "become a pattern" (Tit 2:7); the true way of making men not to despise (slight, or disregard) thy youth. in word--in all that thou sayest in public and private. conversation--that is, "behavior" the Old English sense of the word. in charity . . . faith--the two cardinal principles of the Christian (Gal 5:6). The oldest manuscripts omit, "in spirit." in purity--simplicity of holy motive followed out in consistency of holy action [ALFORD] (Ti1 5:22; Co2 6:6; Jam 3:17; Jam 4:8; Pe1 1:22).

Till I come,.... To Ephesus; where the apostle hoped to be shortly, but was prevented; he afterwards came to Miletus, and sent for the elders of Ephesus thither, when he took his final leave of them. He mentions this circumstance, not as if Timothy was to attend to the following things no longer, but to quicken him to an attendance to them from the consideration of his being shortly with him. Give attendance to reading; that is, of the Scriptures, which the Jews call "reading". (l). "Says R. Tanchum Bar Chanilai, for ever let a man divide his years or life into three parts; one third (let him spend) in the Mikra, (the Scriptures, and the reading of them,) another third in the Misna, and the other third in the Talmud.'' And this is to be understood, not of the reading of the Scriptures in public, for the advantage of others, a custom which obtained in the Jewish synagogues; see Act 13:15 but in private, for his own use and service, that he might be more perfect, and more thoroughly furnished to the work and office to which he was called; for the Scriptures are the fund of spiritual knowledge, as well as the test and standard of doctrine, out of which all must be fetched, and by which it must be tried; and if Timothy, who had known the Scriptures from a child, had been trained up in them, and was always conversant with them, had need to give diligent attention to the reading of them, then much more others: as also to exhortation, to doctrine; as he was privately to read the Scriptures, for his own benefit, he was publicly to expound them, or preach from them, to the advantage of others; for these two, exhortation and doctrine, are branches of the ministerial work, which reading furnishes and qualifies for. "Exhortation" intends the stirring up of believers to the exercise…

Paul here foretels, I. A dreadful apostasy (Ti1 4:1-3). II. He treats of Christian liberty (Ti1 4:4, Ti1 4:5). III. He gives Timothy divers directions with respect to himself, his doctrine, and the people under his care (Ti1 4:6 to the end)

4:12 Be an example: Only those whose lives are shaped by the Good News are worthy teachers of it (cp. 2 Tim 3:10-11; Titus 2:7; Heb 13:7). The false teachers were not.
