Beyond the use of commentaries, another important area in personal Bible study is the use of lexical tools (dictionaries and word study helps). In many cases these reference works are somewhat more objective than commentaries in dealing with the meanings of words and phrases because they are not always directly tied to the meaning of specific passages, but are attempting to cover the range of meaning across numerous passages.

Today I taught my first class of the spring semester, a class in Introduction to New Testament Exegesis (interpretation). I realized this was the 30th year I have taught this course at Dallas Seminary, so counting fall semester sections and summer school, I have probably taught this same course around 60 times.
