Knut Heim examines the literary and historical contexts of wisdom literature, taking the book of Proverbs as a case study, and surveying the work of key scholars in the field. Beginning with literary context, he argues that the sayings are organised into ‘clusters’ through linguistic and thematic links with their neighbours, and that this context has hermeneutical significance. Particularly important is the placement of religious proverbs, which are well integrated with their surroundings. This calls into question the scholarly assumption that religious elements are a late addition to the book, and that wisdom was originally a ‘secular’ endeavour. Rather, elements like the ‘fear of the Lord’ were already embedded within the sayings collections by the time an editor added chapters 1–9. This has implications for the historical development of Proverbs and, more broadly, of wisdom in Israel.
