The following proverb appears in the Bible:

Found in the book of Proverbs, which is a sort of collection of lessons or guidelines by which one should live their life, the proverb essentially means that it is important to be a good and attentive parent.  As the story explains, a good father takes the time to discipline his child and explain to him why his actions were wrong, eliminating the need for physical discipline.  A bad father, on the other hand, would only look to punish his child by spanking him or by other form of physical discipline.  This sort of behavior only alienates the child and drives a distance between father and child, whereas taking the time to teach the child has the dual benefits of sustaining the closeness of the relationship and sparing the child any physical harm.

Interestingly, my friend’s father would always jokingly reverse the saying, as a humorous way of reminding his son to stay in line.
