Job 28:2

but because silver might be first known, or was first in use, especially in the coinage of money; we read of pieces of silver, or shekels of silver, in the times of Abraham, but not of any golden coin, Ge 23:15; and among the old Romans silver was coined before gold ; it has its name from a word which signifies "desire", because it is desirable to men, it answering to various uses and purposes; and sometimes the desires and cravings of men after it are enlarged too far, and become criminal, and so the root of all evil to them: and now there is a "vein" for it in the earth, or a mine in which it may be dug for, and found, in which it runs as veins in a man's body, in certain ramifications, like branches of trees, as they do; and the inhabitants of Hispaniola, and other parts of the West Indies, when found out by Columbus, which abounded with gold mines, declared that they found by experience that the vein of gold is a living tree, (and so the same, perhaps, may be said of silver,) and that it spreads and springs from the root, which they say extends to the centre of the earth by soft pores and passages of the earth, and puts forth branches, even to the uppermost part of the earth, and ceases not till it discovers itself unto the open air; at which time it shows forth certain beautiful colours instead of flowers, round stones of golden earth instead of fruits, and thin plates instead of leaves ; so here there is a vein, or a "going out for the silver" , by which it makes its way, as observed of the gold, and shows itself by some signs and tokens where it may be found; or rather this egress is made for it, by opening the mine where it is, digging into it, and fetching it out of it, and from whence great quantities are often brought.
