Respectfully, I have a different view of this verse. Mine is much in line with Dave Guzik's view. It is based on the context of the entire Psalm, which is an imprecation against wicked judges and rulers. This is why it is so important when studying the Bible that you understand what the circumstances were when something was written. When you see the 58th psalm in its proper context, then everything within the entire psalm flows and fits together.
I highly recommend you take a look at the psalm in Dave's commentary at enduringword.com to get the full picture. But for now, here is an except from the relevant verses in the
Enduring Word commentary on Psalm 58:
(Verses 3-5) A description of the wicked rulers.
The wicked are estranged from the womb;
They go astray as soon as they are born, speaking lies.
Their poison is like the poison of a serpent;
They are like the deaf cobra that stops its ear,
Which will not heed the voice of charmers,
Charming ever so skillfully.
a.
The wicked are estranged from the womb: David diagnosed the problem of the judges; they were
wicked at the root, in their nature, from birth. David understood this of all humanity including himself (
Psalm 51:5).
i. “The description in verses 3ff. is close enough to what is quoted in
Romans 3:10ff. to warn the reader that he faces a mirror, not only a portrait.” (Kidner)
ii. “G.K. Chesterson said that the doctrine of original sin is the only philosophy that has been empirically validated by thirty-five hundred years of human history.” (Boice)
iii. “Sinful, indeed, we are all by nature, and a birth-blot we bring into the world with us, making us strangers and strayers from God.” (Trapp)
iv. In the next few verses, “Figure is heaped on figure in a fashion suggestive of intense emotion.” (Maclaren)
b.
They go astray as soon as they are born, speaking lies: Their corrupt nature was evident early in life, especially in their words. No one has to
teach a child how to lie; with some poetic hyperbole we can say they
are born, speaking lies.
i. “To be untruthful is one of the surest proofs of a fallen state, and since falsehood is universal, so also is human depravity.” (Spurgeon)
c.
Their poison is like the poison of a serpent: The
lies are not harmless; they are like
poison. The words of judges and rulers have special power to oppress others, and their
poison is more deadly. The words of these judges were as dangerous as a deadly, unpredictable
cobra.
i. “The wicked are as dangerous as the venomous cobra that bites his trainer when touched and handled by him.” (VanGemeren)
