Chastened
means,

Disciplined; punished; educated;
afflicted for the purpose of
restraint and correction;

or faults.
" As many as I love
I rebuke and chasten."
Rev 3:19  
...By the word of truth, by the power of God,
by the armour of righteousness on the right hand
and on the left, By honour and dishonour, by evil report, and good report: as deceivers, and yet true;
As unknown, and yet well known; as dying, and, behold, we live; as chastened, and not killed;
As sorrowful, yet alway rejoicing;
as poor, yet making many rich;
as having nothing,   
and yet possessing   
all things.   
2 Cor 6
