Matthew Henry Commentary Exodus 38:9-20

"And he made the court: for the south side southward the hangings of the court were of fine twined linen, a hundred cubits; their pillars were twenty, and their sockets twenty, of brass; the hooks of the pillars and their fillets were of silver. And for the north side a hundred cubits, their pillars twenty, and their sockets twenty, of brass; the hooks of the pillars, and their fillets, of silver. And for the west side were hangings of fifty cubits, their pillars ten, and their sockets ten; the hooks of the pillars, and their fillets, of silver. And for the east side eastward fifty cubits. The hangings for the one side [of the gate] were fifteen cubits; their pillars three, and their sockets three; and so for the other side: on this hand and that hand by the gate of the court were hangings of fifteen cubits; their pillars three, and their sockets three. All the hangings of the court round about were of fine twined linen. And the sockets for the pillars were of brass; the hooks of the pillars, and their fillets, of silver; and the overlaying of their capitals, of silver; and all the pillars of the court were filleted with silver. And the screen for the gate of the court was the work of the embroiderer, of blue, and purple, and scarlet, and fine twined linen: and twenty cubits was the length, and the height in the breadth was five cubits, answerable to the hangings of the court. And their pillars were four, and their sockets four, of brass; their hooks of silver, and the overlaying of their capitals, and their fillets, of silver. And all the pins of the tabernacle, and of the court round about, were of brass." — Exodus 38:9-20 (ASV)

The court's walls, being made only of curtains, indicated that the state of the Jewish church itself was movable and changeable; and that in due time it was to be taken down and folded up, when the place of the tent was to be enlarged and its cords lengthened to make room for the Gentile world.
