The gold and the crystal cannot equal it: and the exchange of it shall not be for jewels of fine gold. 3. זהב Zahab, from זהב zahab, to be Lear, bright, or resplendent: the untarnishing metal; the only metal that always keeps its lustre. But probably here it means gold chased, or that in which precious stones are set; burnished gold.
4. פז Paz, from פז paz, to consolidate, joined here with כלי keley, vessels, ornaments, instruments, etc.: hammered or wrought gold; gold in the finest forms, and most elegant utensils. This metal is at once the brightest, most solid, and most precious, of all the metals yet discovered, of which we have no less than forty in our catalogues. In these verses there are also seven kinds of precious stones, etc., mentioned: onyx, sapphire, crystal, coral, pearls, rubies, and topaz.
These I shall also consider in the order of their occurrence.
Job 28:173. זכוכית zechuchith, Crystal, or glass, from זכה zachah, to be pure, clear, transparent. Crystal or crystal of quartz is a six-sided prism, terminated by six-sided pyramids. It belongs to the siliceous class of minerals: it is exceedingly clear and brilliant, insomuch that this property of it has become proverbial, as clear as crystal.
