70 Heb “wide of soul.” This is an idiom meaning “a greedy person.” The term נֶפֶשׁ (nefesh, traditionally, “soul”) has here its more basic meaning of appetites (a person is a soul, a bundle of appetites; 660 5.a). It would mean “wide of appetite” (רְהַב־נֶפֶשׁ), thus “greedy.”
71 Greed “stirs up” the strife. This individual’s attitude and actions stir up dissension because people do not long tolerate him.
72 The construction uses the participle בּוֹטֵחַ (boteakh) followed by עַל־יְהוָה (’al-yéhvah), which gives the sense of “relying confidently on the Lord.” This is the antithesis of the greedy person who pushes to get what he desires.
73 The verb דָּשֵׁן (dashen) means “to be fat,” and in the Piel/Pual stems “to make fat/to be made fat” (cf. , ). The idea of being “fat” was symbolic of health and prosperity—the one who trusts in the Lord will be abundantly prosperous and fully gratified (cf. “will be enriched”).
74 The idea of “trusting in one’s own heart” is a way of describing one who is self-reliant. C. H. Toy says it means to follow the untrained suggestions of the mind or to rely on one’s own mental resources (Proverbs [], ). It is arrogant to take no counsel but to rely only on one’s own intelligence.
75 The idiom of “walking in wisdom” means to live life according to the acquired skill and knowledge passed on from the sages. It is the wisdom from above that the book of Proverbs presents, not the undisciplined and uninformed wit and wisdom from below.
76 The verb form יִמָּלֵט (yimmalet) is the Niphal imperfect; the form means “to escape.” In this context one would conclude that it means “to escape from trouble,” because the one who lives in this life by wisdom will escape trouble, and the one who trusts in himself will not.
