Charles Ellicott Commentary Psalms 14:1

"The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works; There is none that doeth good." — Psalms 14:1 (ASV)

Fool. —Heb., nabal, from a root meaning “to wither,” hence flat, insipid (insipiens). But this is not therefore speculative atheism, but practical—a denial of the moral government of God—so that fool and wicked become almost synonymous.

They have done abominable works. —Literally, they have made to be abhorred their works. The Septuagint and Vulgate have caught the sense: “They have become abominable in their practices.” Instead of works, Psalms 53:1 has iniquity.
