Psalm 14, attributed to David, provides a sobering reflection on the moral state of humanity and God's searching judgment. It contrasts the folly of those who deny God's existence with the steadfast faith of the righteous, emphasizing divine omniscience, judgment, and the hope for deliverance.

Psalm 14 laments a people who have rejected God––fools who say, “There is no God” (v. 1). It laments the way such people have become corrupt (v. 3) and “eat up (God’s) people” (v. 4). It contrasts those evil people with “the poor” who find their refuge in Yahweh (v. 6)––and God’s people (v. 7).

To the chief Musician, [a Psalm] of David. The argument of this psalm, according to Theodoret, is Sennacherib's invasion of Judea, when he sent Rabshakeh to Hezekiah, with menaces and curses; upon which Hezekiah implored divine help, and obtained it, and the Assyrian army was destroyed by an angel; of all which he thinks this psalm was prophetic.

The apostle, in quoting part of this psalm (Rom 3 10, etc.) to prove that Jews and Gentiles are all under sin (ver 9) and that all the world is guilty before God (ver 19), leads us to understand it, in general, as a description of the depravity of human nature, the sinfulness of the sin we are conceived and born in, and the deplorable corruption of a great part of mankind, even of the world that lies in wickedness, 1 John 5 19.
