'Pure' in the Bible

“Command the Israelites to bring you pure oil from crushed olives for the light, in order to keep the lamp burning continually.

He must continually tend the lamps on the pure gold lampstand in the Lord’s presence.

Arrange them in two rows, six to a row, on the pure gold table before the Lord.

Place pure frankincense near each row, so that it may serve as a memorial portion for the bread and a fire offering to the Lord.
