5:1,2 Respect must be paid to the dignity of years and place. The younger, if faulty, must be rebuked, not as desirous to find fault with them, but as willing to make the best of them. There is need of much meekness and care in reproving those who deserve reproof.
1Ti 5:1-25. General Directions as to How Timothy Should Deal with Different Classes in the Church.
1. an elder—in age; probably not an elder in the ministry; these latter are not mentioned till 1Ti 5:17, "the elders that rule." Compare Ac 2:17, "your old men," literally, "elders." Contrasted with "the younger men." As Timothy was admonished so to conduct himself as to give no man reason to despise his youth (1Ti 4:12); so here he is told to bear in mind his youth, and to behave with the modesty which becomes a young man in relation to his elders.
Rebuke not—literally, "Strike not hard upon"; Rebuke not sharply: a different word from "rebuke" in 2Ti 4:2.
as brethren—and therefore equals; not lording it over them (1Pe 5:1-3).
