Jerome's hermeneutics

Because he [Jerome] is convinced that the overarching biblical narrative is one piece, inspired by the guidance of the Holy Spirit and continually pointing to God’s culminating act in the incarnation and redemptive work of the Son, Jerome consistently looks for connections in the story, many of which are not immediately apparent. He, like other fathers, will force us to read the particular text in light of the whole gospel narrative within the context of the Christian community.

The danger of this approach, though, particularly for those fathers seeking an allegorical sense in the biblical text, is to discern a message in the text that only they can see. The danger of subjectivism is apparent.—Christopher Hall, Reading Scripture with the Church Fathers, 115
