What does paideia mean in Greek?

And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord.

All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him:

If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not?

But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.

Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
