That the biblical wisdom books were read at Qumran is indicated by the presence of fragments of Job (4Q99-101), Proverbs (4Q102103), Qohelet (4Q109-110), and Sirach (2Q18 and 1lQ5 21:11-17; 22:1), as well as 4Q and llQTargums of Job. And it has long been recognized that such core documents of the Qumran library as the Community Rule (IQS) and Thanksgiving Hymns (1QH) contain wisdom elements. But the Qumran library has also yielded other works that appear to be Jewish wisdom texts from the Second Temple period. This paper provides a basic introduction to the corpus of Qumran wisdom texts and discusses why they are important. It uses the device of ten reasons or theses, each of which is stated in a brief sentence and explained at greater length.
