Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
Preach, х Keeruxon (G2784)] - 'Herald.' After "Scripture" (2 Timothy 3:16) comes 'preaching,' to be based on it. [The term for discourses in the synagogue was Daraschoth; the corresponding Greek, dielegeto (G1256) (implying dialectical style, dialogue, and discussion, Acts 17:2; Acts 17:17; Acts 18:4; Acts 18:19), is applied to discourses in the Christian Church]. Justin Martyr ('Apology' 2) describes public worship: 'On Sunday all meet; the writings of the apostles and prophets are read; then the president delivers a discourse; after this all stand up and pray; then there is offered bread and wine and water; the president likewise prays and gives thanks, and the people solemnly assent, saying, Amen.' The bishops and presbyters had the right to preach; but they sometimes called on deacons, and even laymen. Eusebius ('Ecclesiastical History,' 6:19): in this the church imitated the synagogue (Luke 4:17-22; Acts 13:15-16). Be instant - i:e., urgent in thy whole ministry.
In season, out of season - i:e., at all seasons; whether they regard your speaking as seasonable or unseasonable. It will be "in season" to the willing, 'out of season" to the unwilling. 'As the fountains, though none draw from them, still flow on, and the rivers, though none drink of them, still run, so must we do all on our part in speaking, though none give heed to us' (Chrysostom, 'Homily' 30, vol. 5:, p. 221). There is included the idea of times, whether seasonable or unseasonable, to Timothy himself: night as well as day (Acts 20:31), in danger as well as in safety, in prison as well as when at large, not only in church, but everywhere and on all occasions, whenever and wherever the Lord's work requires it.
Reprove - convict.
With - Greek, 'IN (the element in which the "reproving," etc., ought to have place) all long-suffering (2 Timothy 2:24-25; 2 Timothy 3:10) and teaching.' Compare 2 Timothy 2:24, "apt to teach." ["Doctrine" here is didachee (G1322); but in 2 Timothy 3:16, didascalia. Didachee (G1322) is the act; didascalia, the substance or result (Ellicott).]
