Do not withhold correction from a child. If you strike him with a rod, he will not die. Punish him with a rod, and deliver his soul from Sheol. (TLV) Proverbs 23:12-13
Nosh: Although, this is about the disciplining of children, the underlying principle can be applied broadly in our lives. That suffering through a little pain and correction early on, can and will prevent bigger more consequential and distressing mistakes later.
