Paul is speaking of the law of Moses, as the context â€“ both before and after â€“ makes clear. Although verse 9 refers to â€˜lawâ€™ (no article in the Greek, NIV â€“ but see footnote) and not â€˜the lawâ€™, this poses no problem. The fact is, as I explained in chapter 1, the lack of the article strengthens the concept of â€˜the lawâ€™ as the law of Moses. In any case, in verse 8 it is â€˜the lawâ€™. Furthermore, in verse 7, Paul speaks of Judaisers, teachers of the Mosaic law, and in verses 9 and 10, clearly he is referring to the ten commandments. So whatever the passage teaches, it teaches concerning the Mosaic law, including the ten commandments.
