Exodus 27:20-21 - The Lampstand Oil
20 And thou shalt command the children of Israel, that they bring unto thee pure olive oil beaten for the light, to cause a lamp to burn continually. 21 In the tent of meeting, without the veil which is before the testimony, Aaron and his sons shall keep it in order from evening to morning before Jehovah: it shall be a statue for ever throughout their generations on the behalf of the children of Israel.
