Hermeneutics

Etymology of the term comes from 17 century AD to 'interpret'. section 9 of Chapter 1; Gman4326 Confession defines hermeneutics as interpret scripture with scripture as is, or with the help of the Holy Spirit. 9. The infallible rule of interpretation of scripture is the scripture itself; and therefore, when there is a question about the true and full sense of any scripture, (which is not manifold, but one), it must be searched and known by other places that speak more clearly. (2Pe 1:20,21 Ac 15:15,16) 2 peter 1:20,21
  So that ye first know this, that no prophecy of the scripture is of any private interpretation:
For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the divine Ghost.

Hermeneutics is not hard to understand. If you spent memorizing the scriptures or a book/search engine at your disposal. A person can interpret for themselves.
