'Pure' in the Bible

{The length of the portico that [was] in front was the same as the front of the width of the house}: twenty cubits. And its height [was] one hundred and twenty cubits. And he overlaid it on the inside with pure gold.

And the great house [itself] he covered with cypress wood, then he overlaid it with pure gold. And he put on it palm tree [images] and [ornate] chains.

And the king made a large ivory throne and overlaid it with pure gold.

And all the drinking vessels of King Solomon [were] of gold, and all the vessels of the House of the Forest of Lebanon [were] of pure gold. Silver was not valued as anything in the days of Solomon.

They offer burnt offerings to Yahweh {every morning} and {every evening}, sweet spices of incense, and the rows of bread upon the pure table. And the golden lampstand with its lamps [they] keep kindled {every evening}, for we are keeping the requirement of Yahweh our God, but you yourselves have forsaken him.
