Charles H. Spurgeon on Psalms 119:140

Thy word is very pure. In the original, "tried, purified, like gold in the furnace, "absolutely perfect, without the dross vanity and fallibility, which runs through human writings. The more we try the promises, the surer we shall find them. Pure gold is so fixed, Boerhaave, informs us of an ounce of it set in the eye of a glass furnace for two months, without losing a single grain. George Horne.
