18 for I have known that there doth not dwell in me, that is, in my flesh, good: for to will is present with me, and to work that which is right I do not find,
18
For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out.
