Charles Ellicott Commentary Exodus 27:10

"and the pillars thereof shall be twenty, and their sockets twenty, of brass; the hooks of the pillars and their fillets [shall be] of silver." — Exodus 27:10 (ASV)

And the twenty pillars of them ... — Hebrew, and its pillars, twenty (in number), and their bases, also twenty (shall be) of bronze. Kalisch says that the pillars of the court were “of wood, not plated with metal” (Commentary, page 371); but the present passage, and also Exodus 38:10, rightly translated, contradict this view.

The hooks of the pillars. — Compare Exodus 26:37. As the pillars were for the support of the “hangings,” they required “hooks,” to which the “hangings” might be attached.

Their fillets. — Rather, their connecting-rods. The pillars of the court were to be united by rods, which would help to support the “hangings.”
