Job 28:5

5. Turned up as it were fire Same also in the Septuagint. Pliny has a like thought. Ungrateful man repays the debt he owes the earth for bread (Psalms 104:14) by digging out her bowels. The miner probably used fire in his work of excavation, and thus produced effects like those of subterranean fires. In the days of Pliny they broke the rocks with fire and vinegar. Herodotus, (vi, 47,) in his description of “the workings in Thasos” by the Phoenicians, whose home it will be remembered was only about one hundred and eighty miles from Idumaea, states, “that a huge mountain has been turned upside down in the search for ores.”
