Prov 21:25

“Here we have, 1. The miseries of the slothful, whose hands refuse to labour in an honest calling, by which they might get an honest livelihood. They are as fit for labour as other men, and business offers itself, to which they might lay their hands and apply their minds, but they will not; herein they fondly think they do well for themselves, see Pro 26:16. Soul, take thy ease. But really they are enemies to themselves; for, besides that their slothfulness starves them, depriving them of their necessary supports, their desires at the same time stab them. Though their hands refuse to labour, their hearts cease not to covet riches, and pleasures, and honours, which yet cannot be obtained without labour. Their desires are impetuous and insatiable; they covet greedily all the day long, and cry, Give, give; they expect every body should do for them, though they will do nothing for themselves, much less for any body else. Now these desires kill them; they are a perpetual vexation to them, fret them to death, and perhaps put them upon such dangerous courses for the satisfying of their craving lusts as hasten them to an untimely end. Many that must have money with which to make provision for the flesh, and would not be at the pains to get it honestly, have turned highwaymen, and that has killed them. Those that are slothful in the affairs of their souls, and yet have desires towards that which would be the happiness of their souls, those desires kill them, will aggravate their condemnation and be witnesses against them that were convinced of the worth of spiritual blessings, but refused to be at the pains that were necessary to the obtaining of them. 2. The honours of the honest and diligent. The righteous and industrious have their desires satisfied, and enjoy not only that satisfaction, but the further satisfaction of doing good to others. The slothful are always craving and gaping to receive, but the righteous are always full and contriving to give; and it is more blessed to give than to receive. They give and spare not, give liberally and upbraid not; they give a portion to seven and also to eight, and do not spare for fear of wanting.”

“The desire of the slothful killeth him,.... His desire after food and raiment, and riches; for because he cannot have what he desires, being unwilling to work for them, it frets and vexes him to death, or puts him upon unlawful methods to obtain them, which bring him to a shameful death; see Pro 13:4; for his hands refuse to labour; when he is ordered by his superiors, or his wants are such as call for labour; and he seems to be willing and desirous of it, necessity obliging to it, yet he cannot bring his hands to it; these do in effect say, as Aben Ezra observes, Thou shall not do it. Maimonides says this is to be understood of sloth in seeking wisdom (h). (h) Moreh Nevochim, par. 1. c. 34. p. 47.”

“25 The desire of the slothful killeth him; For his hands refuse to be active. The desire of the עצל, Hitzig remarks, goes out first after meat and drink; and when it takes this direction, as hunger, it kills him indeed. But in this case it is not the desire that kills him, but the impossibility of satisfying it. The meaning is simply: the inordinate desire after rest and pleasure kills the slothful; for this always seeking only enjoyment and idleness brings him at last to ruin. תּאוה means here, as in Kibroth ha-tava, Num 11:34, inordinate longing after enjoyments. The proverb is connected by almost all interpreters (also Ewald, Bertheau, Hitzig, Elster, Zckler) as a tetrastich with Pro 21:25 : he (the slothful) always eagerly desires, but the righteous giveth and spareth not. But (1) although צדּיק, since it designates one who is faithful to duty, might be used particularly of the industrious (cf. Pro 15:19), yet would there be wanting in 26a ואין, Pro 13:4, cf. Pro 20:4, necessary for the formation of the contrast; (2) this older Book of Proverbs consists of pure distichs; the only tristich, Pro 19:7, appears as the consequence of a mutilation from the lxx. Thus the pretended tetrastich before us is only apparently such.”
