Parallel
Psalms 13:1
Brenton's English Septuagint · Berean Standard Bible
For the end, a Psalm of David. The fool has said in his heart, There is no God. They have corrupted [themselves], and become abominable in their devices; there is none that does goodness, there is not even so much as one.
14:1
For the choirmaster. Of David. The fool (note: The Hebrew words rendered fool throughout the Psalms denote one who is morally deficient.) says in his heart, “There is no God.” They are corrupt; their acts are vile. There is no one who does good.
