Proverbs 16:27-30

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.
