1 sn Chapter 9 forms the conclusion of the lengthy introduction to the book. Both wisdom and folly will make their final appeals; and both appeal to the simpletons. Wisdom offers life with no mention of pleasure; folly offers pleasure with no mention of death. The first twelve verses concern accepting wisdom: the invitation of wisdom (1-6), the description of the responses (7-11), and the consequence (12). Verses 13-18 concern accepting folly: the invitation (13-17) and the consequence (18).
2 sn Wisdom is personified as a wise woman. She has prepared a house and established it on seven pillars. This is a reference to the habitable world (e.g., 8:31). For the equation of the house and the world, e.g., 8:29; Job 38:6; and Psalm 104:5 (also G. Boström, Proverbiastudien [LUÅ], 1-14). The “seven pillars” have been variously interpreted, but since seven is a number for completeness and sacredness, the idea seems to be that wisdom produced a perfect world.
