“Be thou my strong habitation, whereunto I may continually resort: thou hast given commandment to save me; for thou art my rock and my fortress.”
“Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like: He is like a man which built an house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock.”
“…Remember that it is upon the rock of our Redeemer, who is Christ, the Son of God, that ye must build your foundation; that when the devil shall send forth his mighty winds, yea, his shafts in the whirlwind, yea, when all his hail and his mighty storm shall beat upon you, it shall have no power over you to drag you down to the gulf of misery and endless wo, because of the rock upon which ye are built, which is a sure foundation, a foundation whereon if men build they cannot fall.”
The inner sanctuary was assembled upon a foundation of 104 foundation sockets. The image below shows a likely arrangement of the sockets into which the sideboards would be placed. There were 96 silver sockets for the 48 sideboards, and 4 silver sockets for the four pillars between the holy place and the most holy place. Exodus 38:27 indicates that each one of the sockets was made of one talent of silver. One talent of silver is estimated to equal approximately 75.6 lbs, or 34.27 kg. The total weight of the foundation would therefore be approximately 7,560 lbs or 3,427 kg. This would no doubt serve to hold the tabernacle together in adverse weather conditions. Silver, which has long been used as a precious metal, was donated voluntarily by the children of Israel in order to build the foundation to the house of their King.
The following image is a closer view of the individual sockets. The silver socket design below is based on my calculations of the volume of silver needed to equal one talent. The only exact specification of the sockets is detailed in Exodus 38:27 where the weight of a socket is given as one talent of silver. Based on the common assumption that one talent was equal to 75.6 lbs, and the homogeneity of the element silver, a reasonable volume of such a mass can be estimated. Pure silver has 31.1035 grams of weight per ounce (volume). Using various conversion factors, one talent of silver would have a volume of approximately 1.263 ft^3.
