Adam Clarke on Psalms 53:5

For God hath scattered the bones of him that encampeth against thee: thou hast put them to shame, because God hath despised them - The reader will see, on comparing this with the fifth and sixth verses of Psa 14:1-7, that the words above are mostly added here to what is said there; and appear to be levelled against the Babylonians, who sacked and ruined Jerusalem, and who were now sacked and ruined in their turn. The sixth verse of Psa 14:1-7, "Ye have shamed the counsel of the poor, because the Lord is his refuge," is added here by more than twenty of Kennicott's and De Rossi's MSS.
