Proverbs 26:18

These verses form a tetrastich: 18 As a man who casteth brands, And arrows, and death; 19 So is the man who deceiveth his neighbour, And saith: I only make sport. The old translations of מתלהלה are very diverse. Aquila has rendered it by κακοηθιζόμενος; Symmachus: πειρώμενοι; the Syr.: the vainglorious; the Targ.: מתּחת (from נחת), a successor (spiritually); Jerome: noxius (injurious; for which Luther: secret). There is thus no traditional translation. Kimchi explains the word by השׁתגע (Venet. ἐξεστώς); Aben Ezra by השׁתטה (from שׂטה), to behave thoughtlessly, foolishly; but both erroneously, confounding with it ותּלהּ, Gen 47:13, which is formed from להה and not from לההּ, and is related to לאה, according to which מתלהלה would designate him who exerts himself (Rashi, המתיגע), or who is worn out (Saadia: who does not know what to do, and in weariness passes his time). The root לההּ (להּ), whence the reflex form התלהלהּ, like התמהמהּ, from מההּ, מהּ) leads to another primary idea. The root להּ presents in (Arab.) âliha (vid., Fleischer in the Comm. zur Genesis, p. 57), waliha, and taliha, formed from the 8th form of this verb (aittalah), the fundamental meaning of internal and external unrest; these verbs are used of the effect of fear (shrinking back from fear), and, generally, the want of self-command; the Syr. otlahlah, to be terrified, obstupescere, confirms this primary conception, connecting itself with the R. להּ. Accordingly, he who shoots every possible death-bringing arrow, is thought of as one who is beside himself, one who is of confused mind, in which sense the passive forms of (Arab.) âlah and talah are actually used. Schultens' reference to (Arab.) lâh micare, according to which כמתלהלה must mean sicut ludicram micationem exercens (Bttcher: one who…

See here, 1. How mischievous those are that make no scruple of deceiving their neighbours; they are as madmen that cast firebrands, arrows, and death, so much hurt may they do by their deceits. They value themselves upon it as polite cunning men, but really they are as madmen. There is not a greater madness in the world than a wilful sin. It is not only the passionate furious man, but the malicious deceitful man, that is a madman; he does in effect cast fire-brands, arrows, and death; he does more mischief than he can imagine. Fraud and falsehood burn like fire-brands, kill, even at a distance, like arrows. 2. See how frivolous the excuse is which men commonly make for the mischief they do, that they did it in a jest; with this they think to turn it off when they are reproved for it, Am not I in sport? But it will prove dangerous playing with fire and jesting with edge-tools. Not that those are to be commended who are captious, and can take no jest (those that themselves are wise must suffer fools, Co2 11:19, Co2 11:20), but those are certainly to be condemned who are any way abusive to their neighbours, impose upon their credulity, cheat them in their bargains with them, tell lies to them or tell lies of them, give them ill language, or sully their reputation, and then think to excuse it by saying that they did but jest. Am not I in sport? He that sins in just must repent in earnest, or his sin will be his ruin. Truth is too valuable a thing to be sold for a jest, and so is the reputation of our neighbour. By lying and slandering in jest men learn themselves, and teach others, to lie and slander in earnest; and a false report, raised in mirth, may be spread in malice; besides, if a man may tell a lie to make himself merry, why not to make himself rich, and so truth qui…

26:18-19 Lies are extremely dangerous because they lead people to act on false information. Liars cannot cover up later by claiming that they were only joking (see 6:16-19; 14:5, 25; 25:18).
