'According to the Law' in the Bible

“I am a Jew, born in Tarsus of Cilicia, but brought up in this city, educated under Gamaliel, strictly according to the law of our fathers, being zealous for God just as you all are today.

Then Paul said to him, “God is going to strike you, you whitewashed wall! Do you sit to try me according to the Law, and in violation of the Law order me to be struck?”
