Surely] RM 'For.' Perhaps the question in Job 28:12 and Job 28:20, 'Where shall Wisdom be found?', 'Whence then cometh Wisdom?' may be understood at the beginning of this verse. It has even been suggested that it once stood at the beginning and has been omitted by accident.
Vein] RV 'mine.' Remains of.mines have been found in Edom a little N. of Petra, and it is well known that copper and turquoise mines were worked by the Egyptians in the Sinaitic Peninsula at least as early as the reign of Sa-nekht, the founder of the third Egyptian dynasty, i.e. according to Prof. Flinders Petrie about 4950 b.c. (see his 'Researches in Sinai'). Where they fine it] RV 'which they refine.'
