Septuagint

there is none that does good.   God looked down from heaven upon the sons of men, to see if there were any that understood, or sought after God.  They are all gone out of the way, they are together become unprofitable; there is none that does good, there is not even one

New Testament

as it is written, There is none righteous, no, not one; There is none that understandeth, There is none that seeketh after God;  They have all turned aside, they are together become unprofitable;  There is none that doeth good, no, not so much as one; 

Masoretic Text

There is none that doeth good.  God looked down from heaven upon the children of men, To see if there were any that did understand, That did seek after God.  Every one of them is gone back; they are together become filthy;  There is none that doeth good, no, not one

Comments:  The NT and the LXX agree.  The RSV replaces the ASV’s “filthy” with “corrupt.”  With either rendering, the MT is far from the New Testament’s “unprofitable.”
