and comp. Pliny, h. n. xxxiii. proaem. of mining: imus in viscera ejus [terrae] et in sede Manium opes quaerimus). Most expositors (Hirz., Ew., Hahn, Schlottm., and others) take לכל־תלית adverbially, “to the utmost” or “most closely,” but vid., on Job 26:10; לתכלית might be used thus adverbially, but לכל־תכלית is to be explained according to לכל־רוח, Eze 5:10 (to all the winds).
Verse 4
Job now describes the operation of mining more minutely; and it is worthy of observation that the last-mentioned metal, with which the description is closely connected, is copper. נחל, which signifies elsewhere a valley, the bed of a river, and the river itself, like the Arab. wâdin (not from נחל = נהל, to flow on, as Ges. Thes. and Fürst, but from נחל, root חל to hollow, whence נחילה = חליל, a flute, as being a hollowed musical instrument), signifies here the excavation made in the earth, and in fact, as what follows shows, in a perpendicular direction, therefore the shaft. Nasse contends for the signification “valley,” by which one might very well conceive of “the working of a surface vein:” “By this mode of working, a small shaft is made in the vein (consequently in a perpendicular direction), and the ore is worked from both sides at once. At a short distance from the first shaft a second is formed, and worked in the same way. Since thus the work progresses lengthwise, a cutting becomes formed in the mountain which may well be compared to a deep valley, if, as is generally the case where the stone is firm and the ways are almost perpendicular, the space that is hewn out remains open (that is, not broken in or filled in).” But if נחל everywhere else denotes a valley with its watercourse, it has not necessarily a like signification in mining technology. It signifies, perhaps not without reference to its usual signification, the shafts open above and surrounded by walls of rock (in distinction from the more or less horizontal galleries
