“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.”
King James Version (KJV)
12:11 Now all chastening - Whether from our earthly or heavenly Father, Is for the present grievous, yet it yieldeth the peaceable fruit of righteousness - Holiness and happiness. To them that are exercised thereby - That receive this exercise as from God, and improve it according to his will.
Heb 12:11 No chastening for the present seemeth to be joyous, but grievous. It is never pleasant to endure the chastening, but afterward it yieldeth the peaceable fruit of righteousness. But it afterwards benefits by the holier life it insures. In sorrow we naturally cling closer to God.
