An ungodly man diggeth up evil - How will the following suit?
Effodiuntur opes irritamenta malorum
"Wealth, the incitement to all evil, is digged up out the earth."
A wicked man labors as much to bring about an evil purpose, as the quarryman does to dig up stones.
In his lips - a burning fire - His words are as inflammable, in producing strife and contention among his neighbors, as fire is in igniting dry stubble.
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 Psalm 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.
