Thematic Bible: The measurement of the temple

A reed [as a measuring rod] was then given to me, [shaped] like a staff, and I was told: Rise up and measure the sanctuary of God and the altar [of incense], and [number] those who worship there. But leave out of your measuring the court outside the sanctuary of God; omit that, for it is given over to the Gentiles (the nations), and they will trample the holy city underfoot for 42 months (three and one-half years).
