Refined Silver

Psalm 12:6 “And the words of the LORD are flawless, like silver refined in a furnace of clay, purified seven times.”

Refining of ores containing silver can be accomplished by heating the material to high temperatures in the presence of oxygen or air. Most metals at high temperature are oxidized; however, gold and silver are non-oxidizing metals. If the ore containing silver is placed into a furnace built of clay, the oxidizing metals are absorbed into the clay, leaving a more pure silver residue. Repetition of this process further refines the silver as more of the impurities are absorbed at each step of oxidation, a process is called cupellation.

High purity silver is a valued product, today as well as in the times when David was writing the Psalms. Of much more value than pure silver are the flawless words of God that we find in the scriptures. Whereas the value of silver floats in the marketplace, depending on the current or perceived supply-demand situation, the Word of God is always of infinite value.
When we hear God speak, the smart thing to do is listen and follow what He says.
