'Pure' in the Bible

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

He shall order the lamps upon the pure candlestick before the LORD continually.

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

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