C. F. Keil and Franz Delitzsch on Proverbs 14:11

Pro 14:11 11 The house of the wicked is overthrown;      But the tent of the upright flourishes.

In the cogn. proverb, Pro 12:7, line 2 begins with וּבית, but here the apparently firmly-founded house is assigned to the godless, and on the contrary the tent, easily destroyed, and not set up under the delusion of lasting for ever, is assigned to the righteous. While the former is swept away without leaving a trace behind (Isa 14:23), the latter has blossoms and shoots (הפריח as inwardly transitive, like Job 14:9; Psa 92:14); the household of such remains not only preserved in the same state, but in a prosperous, happy manner it goes forward and upward.
