Between the variants of the Psalms & Romans it would appear that Paul added the words “there is none who seeks after God” when it would also appear he is quoting the psalms:
“God looks down from heaven upon the children of men, To see if there are any who understand, who seek God. Every one of them has turned aside; They have together become corrupt; There is none who does good, No, not one.” Psalms 53:2-3
It says: “everyone one of them has turned aside”
Q: Yet, is there any reason Paul writes it slightly different in Romans?
“As it is written: “There is none righteous, no, not one; There is none who understands; There is none who seeks after God.” Romans 3:10-11
Q2: Is Paul being authorized by the Spirit to write the Psalms slightly differently in Romans?
After all, Paul says “it is written”
