Exodus 27:19

¹⁷All the pillars of the court round about overlaid with silver, and their chapiters silver and their brass sockets.

¹⁸And the length of the court shall be a hundred cubits on each side, and the breadth fifty on each side, and the height five cubits of fine linen spun, and their sockets of brass.

— Exodus 27:19 —

²⁰And do thou charge the children of Israel, and let them take for thee refined pure olive oil beaten to burn for light, that a lamp may burn continually

²¹in the tabernacle of the testimony, without the veil that is before the ark of the covenant, shall Aaron and his sons burn it from evening until morning, before the Lord: it is a perpetual ordinance throughout your generations of the children of Israel.
