Hebrews 12:5-6, 10

and ye have forgotten the exhortation which reasoneth with you as with sons, My son, regard not lightly the chastening of the Lord, Nor faint when thou art reproved of him; For whom the Lord loveth he chasteneth, And scourgeth every son whom he receiveth.

For they indeed for a few days chastened us as seemed good to them; but he for our profit, that we may be partakers of his holiness.
