The bases for the posts were bronze, the hooks and bands were silver, and the plating for the tops of the posts was silver. So all the posts of the courtyard were banded with silver.
The walls of the court, or church-yard, were like the rest curtains or hangings, made according to the appointment, Exo 27:9, etc. This represented the state of the Old Testament church: it was a garden enclosed; the worshippers were then confined to a little compass. But the enclosure being of curtains only intimated that the confinement of the church in one particular nation was not to be perpetual.
Commenting on Exodus 38:9-20
chapiters--or capitals of the pillars, were wooden posts which ran along their top, to which were attached the hooks for the hangings.
The hooks - and their fillets - The capitals, and the silver bands that went round them; see Clarke's note on Exo 26:32.
