What were the sockets of the outer fence and tabernacle parts made of?
The sockets were made of brass or silver. According to the description, the parts of the outer fence and the other tabernacle components were set in sockets made of either brass or silver. This detail reflects the materials used in the tabernacle's construction, distinguishing the metals employed for its foundation and structural supports.
Les explains that all the parts of the outer fence and everything else associated with the tabernacle structure were set in sockets of either brass or silver. He points this out as he moves through the description of the tabernacle's construction, right before discussing the veil that separated the Holy of Holies from the sanctuary (Exodus 36:35). The veil was made of fine twined linen with blue, purple, and scarlet, and it had cherubim woven into it. The context emphasizes the contrast between the outer appearance and the inner beauty of Christ, but the specific materials for the sockets are clearly identified as brass or silver.
