Albert Barnes Commentary Ezekiel 41:16

"the thresholds, and the closed windows, and the galleries round about on their three stories, over against the threshold, ceiled with wood round about, and [from] the ground up to the windows, (now the windows were covered)," — Ezekiel 41:16 (ASV)

Galleries - The upper story of the side-chambers was probably built in the form of an open gallery.

Over against the door - The rows of the side-chambers extended to the front of the temple, so that they were “over against” the opening, but did not extend as far as the porch.

Ceiled - Overlaid. Pillars, galleries, narrow windows were overlaid with wood (1 Kings 6:15–16).

Were covered - With wood.
