Proverbs 18:11

11 The possession of the righteous is his strong fort, And is like a high wall in his imagination. Line first = Pro 10:15. משׂכּית from שׂכה, Chald. סכה(whence after Megilla 14a, יסכּה, she who looks), R. שׂך, cogn. זך, to pierce, to fix, means the image as a medal, and thus also intellectually: image (conception, and particularly the imagination) of the heart (Psa 73:7), here the fancy, conceit; Fleischer compares (Arab.) tṣwwr, to imagine something to oneself, French se figurer. Translators from the lxx to Luther incorrectly think on שׂכך (סכך), to entertain; only the Venet. is correct in the rendering: ἐν φαντασίᾳ αὐτοῦ; better than Kimchi, who, after Ezr 8:12, thinks on the chamber where the riches delighted in are treasured, and where he fancies himself in the midst of his treasures as if surrounded by an inaccessible wall.

Having described the firm and faithful defence of the righteous man (Pro 18:10), Solomon here shows what is the false and deceitful defence of the rich man, that has his portion and treasure in the things of this world, and sets his heart upon them. His wealth is as much his confidence, and he expects as much from it, as a godly man from his God. See, 1. How he supports himself. He makes his wealth his city, where he dwells, where he rules, with a great deal of self-complacency, as if he had a whole city under his command. It is his strong city, in which he intrenches himself, and then sets danger at defiance, as if nothing could hurt him. His scales are his pride; his wealth is his wall in which he encloses himself, and he thinks it a high wall, which cannot be scaled or got over, Job 31:24; Rev 18:7. 2. How herein he cheats himself. It is a strong city, and a high wall, but it is so only in his own conceit; it will not prove to be really so, but like the house built on the sand, which will fail the builder when he most needs it.
