Romans 2:17-20

Mace(i) 17 'Tis true, you bear the name of a Jew, you depend upon the law, and boast of your worship: 18 you know the divine will, and what is contrary thereto, having been educated in the law: 19 you think you are a guide to the blind, a light to those who are in darkness, 20 an instructer of the ignorant, a teacher to the weak, because you have a clear view of the true meaning of the law.
