Exodus 27:18-22

The length of the courtyard shall be a hundred cubits, and the width fifty throughout, and the height five cubits of fine twisted linen, and their bases of bronze.

All the utensils of the tabernacle used in all its service, and all its pegs, and all the pegs of the courtyard, shall be of bronze.

“And you shall command the sons of Israel that they bring you clear oil of beaten olives for the light, to make a lamp burn continually.

In the tent of meeting, outside the veil which is before the testimony, Aaron and his sons shall keep it in order from evening to morning before the Lord; it shall be a permanent statute throughout their generations for the sons of Israel.
