He shutteth his eyes to devise froward things: moving his lips he bringeht evil to pass.
– Proverbs 16:30
Verses 27-30 are a group of proverbs about trouble makers. This proverb ends the group. Reference to eyes and lips means facial expressions or gestures. These gestures either serve to deceive or to convey some malignant purpose (Proverbs 6:13-14; 10:10). If connected with enticement in the previous proverb, he is masking the evil of his way and persuading his neighbor.
