Exegetics not only explains ancient meanings, but also analyzes grammatical and rhetorical phenomena in ancient books.
Studying ancient literature from the perspective of language is helpful for people to read classical literature.
Exegetics can be divided into broad sense and narrow sense.
In a broad sense, exegetics includes phonology and philology, while in a narrow sense, exegetics is only a discipline opposite to phonology and writing in primary school.
Some people also divide exegetics into old and new.
