Context

[17:22] 1 sn Heb “a heart of rejoicing”; KJV “a merry heart”; NAB, NASB “a joyful heart.” This attributive genitive refers to the mind or psyche. A happy and healthy outlook on life brings healing.
[17:22] 2 tc The word “healing” is a hapax legomenon; some have suggested changes, such as to Arabic jihatu (“face”) or to גְּוִיָּה (gÿviah, “body”) as in the Syriac and Tg. Prov 17:22, but the MT makes sense as it is and should be retained.
[17:22] 3 sn The “crushed spirit” refers to one who is depressed (cf. NAB “a depressed spirit”). “Crushed” is figurative (an implied comparison) for the idea that one’s psyche or will to go on is beaten down by circumstances.
[17:22] 4 sn The “bones” figuratively represent the whole body encased in a boney framework (metonymy of subject). “Fat bones” in scripture means a healthy body (3:8; 15:30; 16:24), but “dried up” bones signify unhealthiness and lifelessness (cf. Ezek 37:1-4).
[18:14] 5 tn Heb “the spirit of a man.” Because the verb of this clause is a masculine form, some have translated this line as “with spirit a man sustains,” but that is an unnecessary change.
[18:14] 6 sn This is a rhetorical question, asserting that very few can cope with depression.
[18:14] 7 sn The figure of a “crushed spirit” (ASV, NAB, NCV, NRSV “a broken spirit,” comparing depression to something smashed or crushed) suggests a broken will, a loss of vitality, despair, and emotional pain. In physical sickness one can fall back on the will to live; but in depression even the will to live is gone.
[25:14] 9 sn The emblem now is one of clouds and winds that would be expected to produce rain; they gain attention and raise people’s expectations but prove to be disappointing when no rain is forthcoming, and hence could be thought of as deceitful.
[25:14] 10 tn The form מִתְהַלֵּל (mithallel) is the Hitpael participle of the well-known word for “praise”; but in this stem it means “to praise oneself” or “to boast.” The description of “windbag” seems appropriate in this context.
[25:14] 11 tn Heb “a gift of falsehood.” This would mean that the individual brags about giving a gift, when there is no gift.
