Proverbs 6:13
He winketh with his eyes, he speaketh with his feet, he teacheth with his fingers;
Be careful with body language. Wicked persons often hide bad intentions behind eye, hand, or feet movements. Rather than state their evil goals and be rejected as dangerous, they use indirect methods for their wickedness. A wise man will learn to recognize these hypocrites, even though they make efforts to cover their malicious designs. All noble persons should reject such secret methods and make their good intentions easily known.
