For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:
To keep thee from the evil woman, from the flattery of the tongue of a strange woman. Lust not after her beauty in thine heart; neither let her take thee with her eyelids. For by means of a whorish woman a man is brought to a piece of bread: and the adultress will hunt for the precious life.
In these verses, Solomon returns to a familiar theme in his book of wisdom — a warning for his sons (or young men in general) to avoid a sexually promiscuous woman, whether married or unmarried.
This time, he tells the reader to take heed to his instruction because it will keep him away from such a woman’s grasp. It will help him avoid being taken in by her flattery and flirtatious ways. It will keep him out from under the spell cast by her eyes.
Solomon even tells him not to lust after this woman in his heart. With pornography and excessive sex appeal in video games, movies, TV, and advertisements, this advice is more relevant than ever. It’s easy for the heart to get carried away. It’s easy for our thoughts to run wild. But sin begins in the heart and the mind long before it manifests in the body.
If we can learn to harness the thoughts of our heart, we can save ourselves a lot of trouble.
