They are all gone aside, they are all together become filthy: there is none that doeth good, no, not one.
They are all gone aside - the condition by nature of all without exception: "children of men" (Psalms 14:2). "The generation of the righteous" (Psalms 14:5) also "were by nature the children of wrath, even as others" (Ephesians 2:3). Grace makes the difference between them and the general mass. The children of grace are comparatively few (Matthew 7:14). He accumulates words to express the wide prevalence of the corruption, "all (literally, 'the all:' the whole of humanity) ... together ... there is none that doeth good, no not one." Their 'going aside' or "away" (from God) stands in contrast to 'seeking the Lord.'
They are all together become filthy - literally, 'become rancid' х 'aalach (H444), Job 15:16]. Paul adds to his quotation from this psalm, verses quoted from various other parts of Scripture (Romans 3:13-18). Hence, transcribers have added the same words as parts of this 14th Psalm in the margin of the Vatican, the Septuagint, and in some of the Latin versions, not perceiving that the apostle's quotation was not limited to this psalm.
Suicidal blindness of the workers of iniquity in assailing the Lord's people, and so bringing destruction on themselves from the Lord.
