Proverbs 16:30

“He shutteth his eyes--denoting deep thought (Psa 64:6). moving his lips--or, "biting his lips"--a determined purpose (Pro 6:13).”

“The four verses speak of the same thing, and the well-known opprobrious name, the “man of Belial,” stands at the head as stigmatizing the man who delights in causing the mischief of which they treat. Diggeth up evil - i. e., Digs an evil pit for others to fall into. Compare Psalms 7:15. Proverbs 16:30 The physiognomy of the man of Belial, the half-closed eyes that never look you straight in the face, the restlessness or cunning of which biting the lips is the surest indication. Compare Proverbs 6:13. return to 'Top of Page'”

“Shutteth - That his thoughts may be more intent. Moving - Which is the gesture of one whose thoughts are deeply engaged. Proverbs 16:32”

“shutteth: Pro 6:12-14, Pro 10:10; Isa 6:10; Mat 13:15; Joh 3:20 moving: Pro 16:27; Mic 7:3; Mat 14:7, Mat 14:8, Mat 27:23-26 Proverbs 16:31”

“30 He who shutteth his eyes to devise falsehood; He who biteth his lips bringeth evil to pass. A physiognomical Caveto. The ἁπ. λεγ. עצה is connected with עצם, Isa 33:15 (Arab. transp. ghamḍ), comprimere, formed from it. Regarding קרץ of lips or eyes, vid., p. 144; the biting of the lips is the action of the deceitful, and denotes scorn, malice, knavery. The perf. denotes that he who is seen doing this has some evil as good as accomplished, for he is inwardly ready for it; Hitzig suitably compares Sa1 20:7, Sa1 20:33. Our editions (also Lwenstein) have כּלּה, but the Masora (vid., Mas. finalis, p. 1) numbers the word among those which terminate in א, and always writes כּלּא. Proverbs 16:31”
