'Pure' in the Bible

As to the porch that is on the front, the length is by the front of the breadth of the house, twenty cubits, and the height a hundred and twenty, and he overlayeth it within with pure gold.

And the king maketh a great throne of ivory, and overlayeth it with pure gold;

and are making perfume to Jehovah, burnt-offerings morning by morning, and evening by evening, and perfume of spices, and the arrangement of bread is on the pure table, and the candlestick of gold, and its lamps, to burn evening by evening, for we are keeping the charge of Jehovah our God, and ye -- ye have forsaken Him.
