pillars
The fillets and hooks upholding the linen hangings are of silver
( See Scofield) - (Exodus 38:27)
for it is in virtue of His redemptive work that Christ is our way of access, and not by virtue of His righteous life (symbolized by the fine linen); but the pillars of the court rest upon brass sockets, not silver as in the case of the boards
( See Scofield) - (Exodus 26:19)
and brass symbolizes divine righteousness in judgment
( See Scofield) - (Numbers 21:9).
Redemption not only displays God's mercy, but vindicates His righteousness in showing that mercy. (Romans 3:21-26).
