As with other wisdom books, there is no easily recognizable structure in Sirach; in many parts it is difficult to discover a logical progression of thought or to discern the principles of arrangement. However, a series of six poems about the search for and attainment of wisdom (1:1–10, 4:11–19; 6:18–37; 14:20–15:10; 24:1–33; and 38:24–39:11) divide the book into something resembling chapters, although the divisions are not thematically based. The exceptions are the first two chapters, whose reflections on wisdom and fear of God provide the theological framework for what follows, and the last nine chapters, which function as a sort of climax, first in an extended praise of God’s glory as manifested through creation (42:15–43:33) and second in the celebration of the heroes of ancient Israel’s history dating back to before the Great Flood through contemporary times (see previous section).
