Typology in Christian theology and biblical exegesis is a doctrine or theory concerning the relationship of the Old Testament to the New Testament. Events, persons or statements in the Old Testament are seen as types prefiguring or superseded by antitypes, events or aspects of Christ or his revelation described in the New Testament. For example, Jonah may be seen as the type of Christ in that he emerged from the fish's belly and thus appeared to rise from death.

Christians believe that Jesus is the mediator of the New Covenant. In the Sermon on the Mount he commented on the Law. Some scholars consider this to be an antitype of the proclamation of the Ten Commandments or Mosaic Covenant by Moses from Mount Sinai.
The Brazen Serpent monument by Giovanni Fantoni is located at Mount Nebo. Its shape also references a crucifix.
Exegesis is a critical explanation or interpretation of a text. The term is traditionally applied to the interpretation of Biblical works. In modern usage, exegesis can involve critical interpretations of virtually any text, including not just religious texts but also philosophy, literature, or virtually any other genre of writing. The phrase Biblical exegesis can be used to distinguish studies of the Bible from other critical textual explanations.
