What does Proverbs 6:25 mean?

Solomon recognized the role of the heart in making moral decisions. If we love God with all our heart, we can lead a moral life, but if we yield to lust in our heart, we will commit sin. Therefore, Solomon tells his son not to desire the evil woman's beauty in his heart. Proverbs 31:30 says "beauty is vain." It is worth nothing if it lacks godliness. First Peter 3:4 tells women: "Let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious." A truly beautiful woman, therefore, is beautiful on the inside. A man who falls for the beauty of a temptress—or a woman for a handsome man—may discover quickly and too late that attractiveness is a façade that hides an ugly and painful trap.

Solomon also advises his son to avoid becoming captured by the evil woman's eyelashes. The reference here is to some attractive feature or lure—as is often portrayed when a woman "bats her eyes" or flutters her eyelashes. That may attract a man, but if her come-hither glances catch him, he may feel like an unwary insect captured by a Venus flytrap.
