'Pure' in the Bible

Command the children of Israel, that they bring unto thee pure olive oil beaten for the light, to cause a lamp to burn continually.

He shall keep in order the lamps upon the pure candlestick before Jehovah continually.

And thou shalt set them in two rows, six on a row, upon the pure table before Jehovah.

And thou shalt put pure frankincense upon each row, that it may be to the bread for a memorial, even an offering made by fire unto Jehovah.
