'Train' in the Bible

Therefore it says,“When He ascended on high,He led captivity captive,And He bestowed gifts on men.”

Let the [spoken] word of Christ have its home within you [dwelling in your heart and mind—permeating every aspect of your being] as you teach [spiritual things] and admonish and train one another with all wisdom, singing psalms and hymns and spiritual songs with thankfulness in your hearts to God.

But have nothing to do with irreverent folklore and silly myths. On the other hand, discipline yourself for the purpose of godliness [keeping yourself spiritually fit].

so that they may encourage the young women to tenderly love their husbands and their children,

You must submit to [correction for the purpose of] discipline; God is dealing with you as with sons; for what son is there whom his father does not discipline?
