PSALM 4:8 I will both lay me down in peace, and sleep:

As a jewel of gold in a swine’s snout, so is a fair woman which is without discretion.   A good thing in a bad place The Jews regarded the pig as an unclean animal. The heathen around worshipped the pig, and they ate it afterwards as an act of worship. The Egyptians, when they wished to draw a picture of a very foolish person, always represented him as a pig. How unlovely is the idea of a jewel that might have been worn by a queen being placed in the nose of a pig! But there are some things that we see every day which are quite as bad. For instance-- 1. A pretty face and a very ugly soul. It is nice to be beautiful, but it is far better to be good. When you feel tempted to be proud because you are good-looking, ask yourself, “Is my soul good-looking and beautiful to God?” 2. A good head and a bad heart. King John, one of England’s worst kings, was a very clever man. It is not enough to be learned, or to have great talents; we want to be holy, and then shall we be able to use our abilities well. 3. Wise words and foolish deeds. It was said of a certain king, that “he never said a foolish thing and never did a wise one.” A jewel treated as described in this text would be a jewel misapplied. It was never intended for such a use. And God did not intend that we should ever waste our minds and our time in the service of sin. The Jews had a saying that the nose of a pig is walking dirt. If a jewel were placed in it, it would be spoiled. Sin mars a beautiful face; it will even make a clever man foolish; it will ruin us if it be not taken away from us. (J. J. Ellis.)
