He winketh with his eyes, he speaketh with his feet, he teacheth with his fingers;
– Proverbs 6:13
This verse refers to different physical gestures employed by the wicked man. The precise meaning or description of each gesture is not important, but rather that they are used to deceive. Such gestures are a part of his salesmanship, whether he is extorting or coercing. The previous verse referenced his forward mouth and the next his devised mischief. The whole picture of the wicked man is one who continually seeks to lead others astray and take advantage of them one or another.
