I know that nothing good lives in me, that is, in my flesh; for I have the desire to do what is good, but I cannot carry it out.
KJV
For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but [how] to perform that which is good I find not.
ASV
For I know that in me, that is, in my flesh, dwelleth no good thing: for to will is present with me, but to do that which is good is not.
