The lampstand

The lamp stand in Old Testament is interesting. The design is patterned after an almond tree. The first trees in the Near East to blossom in spring. The cups of of the lamp stand resemble either the almond nut.
The number seven signifying completeness. The ancient lamp was a small clay saucer with part of its rims pinched together to form a spout from which protruded the top of a wick fed by oil contained the saucer. The ruins of Beth Shan and Megiddo have given examples of a mental pedestal includes a ledge designed to carry a lamp. Oil for the lamps was to be supplied by the people; the light from the lamps represented the glory of the Lord reflected in the consecrated lives of the Israelite. Israel's glory answering to God's glory in the tabernacle. This passages is quoted in the Book of Hebrew. The Old Covenant is completed in the New Covenant.

  

Exodus 25:31-40

 

³¹ “Make a lampstand of pure gold. Hammer out its base and shaft, and make its flowerlike cups, buds and blossoms of one piece with them. ³² Six branches are to extend from the sides of the lampstand—three on one side and three on the other. ³³ Three cups shaped like almond flowers with buds and blossoms are to be on one branch, three on the next branch, and the same for all six branches extending from the lampstand. ³⁴ And on the lampstand there are to be four cups shaped like almond flowers with buds and blossoms. ³⁵ One bud shall be under the first pair of branches extending from the lampstand, a second bud under the second pair, and a third bud under the third pair—six branches in all. ³⁶ The buds and branches shall all be of one piece with the lampstand, hammered out of pure gold.
³⁷ “Then make its seven lamps and set them up on it so that they light the space in front of it. ³⁸ Its wick trimmers and trays are to be of pure gold. ³⁹ A talent  of pure gold is to be used for the lampstand and all these accessories. ⁴⁰ See that you make them according to the pattern shown you on the mountain.

Hebrews 8:5

 They serve at a sanctuary that is a copy and shadow of what is in heaven. This is why Moses was warned when he was about to build the tabernacle: “See to it that you make everything according to the pattern shown you on the mountain.”
