Charles Ellicott Commentary Psalms 53:1

"The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity; There is none that doeth good." — Psalms 53:1 (ASV)

And.—The conjunction is missing in Psalm 14:1.

Iniquity.—Instead of the general term “doings,” in Psalm 14:1, it is as if the adapter of the Psalm felt that a word applicable to good as well as evil was not strong enough to express the hideousness of the profanity.
