1 Tim 4:12-13
"Let no one despise you for your youth, but set the believers an example in speech, in conduct, in love, in faith, in purity. Until I come, devote yourself to the public reading of Scripture, to exhortation, to teaching."
Timothy was young (~30 years) in a culture that valued age. Paul instructs him not to allow himself to be despised — not out of arrogance, but by being an example in six areas: speech, conduct, love, spirit, faith, purity. The ministry of public reading of Scripture was central in early worship.
