'Chastening' in the Bible

and ye have forgotten the exhortation that doth speak fully with you as with sons, 'My son, be not despising chastening of the Lord, nor be faint, being reproved by Him,

if chastening ye endure, as to sons God beareth Himself to you, for who is a son whom a father doth not chasten?

and if ye are apart from chastening, of which all have become partakers, then bastards are ye, and not sons.

for they, indeed, for a few days, according to what seemed good to them, were chastening, but He for profit, to be partakers of His separation;

and all chastening for the present, indeed, doth not seem to be of joy, but of sorrow, yet afterward the peaceable fruit of righteousness to those exercised through it -- it doth yield.
