A.T. Robertson Commentary Galatians 2:19

"For I through the law died unto the law, that I might live unto God." — Galatians 2:19 (ASV)

I through the law died to the law (εγω δια νομου νομω απεθανον). Paradoxical, but true. See Rom 7:4,6 for picture of how the law waked Paul up to his real death to the law through Christ.
