Exodus 27:20-21

New Century Version

Oil for the Lamp

²⁰ “Command the people of Israel to bring you pure olive oil, made from pressed olives, to keep the lamps on the lampstand burning. ²¹ Aaron and his sons must keep the lamps burning before the Lord from evening till morning. This will be in the Meeting Tent, outside the curtain which is in front of the Ark. The Israelites and their descendants must obey this rule from now on.
