Exodus 27:20-21

New Revised Standard Version Catholic Edition

The Oil for the Lamp

²⁰ You shall further command the Israelites to bring you pure oil of beaten olives for the light, so that a lamp may be set up to burn regularly. ²¹ In the tent of meeting, outside the curtain that is before the covenant,^[a] Aaron and his sons shall tend it from evening to morning before the Lord. It shall be a perpetual ordinance to be observed throughout their generations by the Israelites.
