'Doctrine' in the Bible

As I urged you when I was on my way to Macedonia, stay on at Ephesus so that you may instruct certain individuals not to teach any different doctrines,

for sexually immoral persons, for homosexuals, for kidnappers and slave traders, for liars, for perjurers—and for whatever else is contrary to sound doctrine,

Until I come, devote yourself to public reading [of Scripture], to preaching and to teaching [the sound doctrine of God’s word].
