'Chastening' in the Bible

Behold, happy is the man whom God correcteth: therefore despise not thou the chastening of the Almighty:

My son, despise not the chastening of the LORD; neither be weary of his correction:

LORD, in trouble have they visited thee, they poured out a prayer when thy chastening was upon them.

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?

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.
