Matthew 7:6

Matthew 7:6. Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.

Zeal should always be tempered by prudence. There are times when it would be treason to truth to introduce it as a topic of conversation,-when men are in such a frame of mind that they will be sure rather to cavil at it than to believe it. Not only speak thou well, but speak thou at the right time, for silence is sometimes golden. See that thou hast thy measure of golden silence as well as of silver speech.
