“Do not give what is sacred to the dogs and do not cast your pearls before swine.”
“Unless one be asked, one must not explain anything to anybody nor must one answer a person who asks improperly. Let a wise man, although he knows the answer, behave among men as though he were an idiot. Of the two persons, him who illegally explains and him who illegally asks, one or both will die or incur the others’ enmity. Where merit and wealth are not obtained by teaching nor at least due obedience, in such soil, sacred knowledge must not be sown, just as good seed must not be thrown on barren land.”
