Ezekiel 40:10

The measurer, having passed through the whole length of the gateway E. to W., and named each particular thing on one side of it, viz. threshold (Ezekiel 40:6), guardroom (Ezekiel 40:7), wall space between guardrooms (Ezekiel 40:7), inner threshold to porch (Ezekiel 40:7), porch and its posts (Ezekiel 40:8), with their dimensions, now states that there were three guardrooms on each side, all of the same size, and also some other points. For little chambers, guardrooms.

the posts had one measure Probably the "posts" here are not the jambs of the door of the porch (Ezekiel 40:9), but the wall-fronts or spaces between the guardrooms (Ezekiel 40:7), Fig, 1, gh, ik. There were two of these on each side of the passage, each measuring five cubits.
