Exodus 27:20-21 - The Lampstand Oil
20 "And command the children of Israel that they give the pure oil olive beaten for the lights to pour always into the lamps. 21 In the tabernacle of witness without the veil which is before the witness, shall Aaron and his sons dress it both even and morning before the LORD: And it shall be a duty for ever unto your generations after you: to be given of the children of Israel."
