Exodus 27:17

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).
