Exodus 27:16–21

16 For the gate of the court there shall be a screen twenty cubits long, of blue and purple and scarlet yarns and fine twined linen, embroidered with needlework. It shall have four pillars and with them four bases. 17 All the pillars around the court shall be filleted with silver. Their hooks shall be of silver, and their bases of bronze. 18 The length of the court shall be a hundred cubits, the breadth fifty, and the height five cubits, with hangings of fine twined linen and bases of bronze. 19 All the utensils of the tabernacle for every use, and all its pegs and all the pegs of the court, shall be of bronze.

Oil for the Lamp

20 “You shall command the people of Israel that they bring to you pure beaten olive oil for the light, that a lamp may regularly be set up to burn. 21 In the tent of meeting, outside the veil that is before the testimony, Aaron and his sons shall tend it from evening to morning before the LORD. It shall be a statute forever to be observed throughout their generations by the people of Israel.
