Exodus 27 Pure olive oil

Exodus 27
Pure olive oil
20 And thou command the children of Israel that they bring thee pure oil olive beaten for the Candieiro; to burn the lamps continuously.
21 In the tent of meeting, outside the veil, which is before the testimony, Aaron and his sons shall order it from evening to morning before the Lord, a perpetual statute throughout their generations is this, the children of Israel.
