Proverbs 6:13

He winketh with his eyes, he speaketh with his feet, he teacheth with his fingers;

He winketh with his eyes, he speaketh with his feet, he teacheth with his fingers. He makes secret signs with all these members; the mark of a deceitful and malignant man (Proverbs 10:10; Psalms 35:19, "Neither let them wink with the eye that hate me"). When he dare not speak openly, he expresses by a sign the wicked deed that he wants to be done. Compare on "teacheth" - i:e., gives instructions to his tools what is to be done - "with his fingers," Isaiah 58:9, "The putting forth of the finger, and speaking vanity." Besides his month, he lays himself out wholly, by gesticulation with every member, to impose. 'Thus we see the idle [ argous (G692)] to be over-busy [periergous], and those who will not move even their little finger to any good work, to be very energetic in badness'

(T. Cartwright).
