Sockets

Sockets [1]
Exodus 26:19 (c) (See under SILVER).
Song of Solomon 5:15 (c) The legs support the body and strong legs are necessary to success for the runner, the wrestler, the prize fighter, and all of those who use the legs constantly in their vocations. Evidently the spiritual meaning of the passage is that our Lord JESUS CHRIST, concerning whom this passage was written, will never fail, will never weaken, and they in turn are supported by the pure gold of Deity. The sockets sustain the legs and enable them to work properly. The Deity of CHRIST makes all this true and possible.
