Job 6:18

“The paths of their way are turned aside, etc.] That is, the waters, when melted by the heat of the sun, and the warmth of the weather, run, some one way, and some another in little streams and windings, till they are quite lost and the tracks of them are no more to be seen; denoting that all appearance of friendship was quite gone, and no traces of it to be found: they go to nothing, and perish: some of them are lost in little meanders and windings about, and others are exhaled by the heat of the sun, and go into “Tohu”, as the word is, into empty air; so vain and empty, and perishing, were all the comforts he hoped for from his friends; though some understand this of the paths of travellers…”

“turned aside--rather, "caravans" (Hebrew, "travellers") turn aside from their way, by circuitous routes, to obtain water. They had seen the brook in spring full of water: and now in the summer heat, on their weary journey, they turn off their road by a devious route to reach the living waters, which they remembered with such pleasure. But, when "they go," it is "into a desert" [NOYES and UMBREIT]. Not as English Version, "They go to nothing," which would be a tame repetition of the drying up of the waters in Job 6:17; instead of waters, they find an "empty wilderness"; and, not having strength to regain their road, bitterly disappointed, they "perish." The terse brevity is most expressive.”

“The paths of their way are turned aside - Noyes renders this, “The caravans turn aside to them on their way.” Good, “The outlets of their channel wind about.” Rosenmuller, “The bands of travelers direct their journey to them.” Jerome, “Involved are the paths of their steps.” According to the interpretation of Rosenmuller, Noyes, Umbreit, and others, it means that the caravans on their journey turn aside from their regular way in order to find water there; and that in doing it they go up into a desert and perish. According to the other interpretation, it means that the channels of the stream wind along until they diminish and come to nothing. This latter I take to be the true sense of the…”

“Perish - They are gone out of their channel, flowing hither and thither, 'till they are quite consumed. Job 6:19”

“18 The paths of their course are turned about, They go up in the waste and perish. 19 The travelling bands of Tma looked for them, The caravans of Saba hoped for them; 20 They were disappointed on account of their trust, They came thus far, and were red with shame. As the text is pointed, ארחות, Job 6:18, are the paths of the torrents. Hitz., Ew., and Schlottm., however, correct ארחות, caravans, which Hahn even thinks may be understood without correction, since he translates: the caravans of their way are turned about (which is intended to mean: aside from the way that they are pursuing), march into the desert and perish (i.e., because the streams on which they reckoned are dried up). So, in…”
