The guardroom was one rod long and one rod wide

I have always found the temple measurements in Ezekiel 40-42 to be rather obscure. Why are these measurements supposed to be important enough to keep track of? They are clearly for a future or a possible temple, not one that existed then or since.

Revelation echoes this, with a twist: "Get up and measure the temple of God and the altar, and those who worship in it. Leave out the court which is outside the temple and do not measure it, for it has been given to the nations". That's suggestive: measurement relates to possession or ownership, perhaps? God owns it in the ultimate sense, but the temple is for the worshippers.

In Genesis there's a different kind of "measurement"; a measurement by foot, and one that puts Abraham in the place he/his is to possess. "Arise, walk about the land through its length and breadth; for I will give it to you."

I have no clue what the measurement numbers are supposed to signify in Ezekiel (if it's a physical future temple, why? in light of Hebrews 10), but I like the idea that measurement might signify "we are there." Measuring is something people do, even if is only "how many of us fit."
