Commentaries:
Adam Clarke
They are all gone aside - They will not walk in the straight path. They seek crooked ways; and they have departed from truth, and the God of truth.
They are all together become filthy - neelachu . They are become sour and rancid; a metaphor taken from milk that has fermented and turned sour, rancid, and worthless.
There is none that doeth good, no, not one - This is not only the state of heathen Babylon! but the state of the whole inhabitants of the earth, till the grace of God changes their heart. By nature, and from nature, by practice, every man is sinful and corrupt. He feels no good; he is disposed to no good; he does no good. And even God himself, who cannot be deceived, cannot find a single exception to this! Lord, what is man?
The Vulgate, the Roman copy of the Septuagint, the Athtopic, and the Arabic, add those six verses here which are quoted by St. Paul, Romans 3:13-18 (note). See the observations at the end of this Psalm.
