If you are going to use Proverbs as the foundation for your belief on this, I will challenge you to consider starting with stoning fools and cutting out your tounge for speaking lies FIRST. My only caution is that unlike a child, fools are not helpless and sometimes they wise up and start returning fire.
Be very careful what wisdom literature you decide to take on face value and which you decide are 'proverbial'.
My rule of thumb has always been to take a piece of scripture to the 'foot of the cross' and see how it compares to the gospel of Christ. Does inflicting physical pain mesh with the patient discipling that Christ displayed? Does inflicting physical pain truely teach the objective attempted or does it teach fear?
