'Pure' in the Bible

And the oracle within was twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof; and he overlaid it with pure gold; and he overlaid the cedar-wood altar --

and Solomon overlaid the house within with pure gold, and shut off the oracle in front with chains of gold, and overlaid it with gold.

and the candlesticks of pure gold, five on the right, and five on the left, before the oracle; and the flowers, and the lamps, and the tongs of gold,

and the basons, and the knives, and the bowls, and the cups, and the censers of pure gold; and the hinges of gold, for the folding-doors of the inner house, the most holy place, and for the doors of the house, of the temple.
