λάμπει [3 verses](3rd sg pres ind act) "It giveth light" is lampo, which means "to shine forth," "to ring loud and clear," and "to illuminate." -- (CW) The word translated as "gives light" is better translated as  "shines out" or "illuminates." It does not contain either the words "give" or "light." The Greek word used here is the source of our word "lamp."
