1 A reed like a rod was given to me. One said, “Rise, and measure God’s temple, and the altar, and those who worship in it.
there was given to me a measuring rod – this brings us back to Ezek 40:3, and the vision of a man with the appearance of bronze, having a measuring rod to measure the temple. The measurements, from Ezek 43:11, are the boundaries of the sanctified Church. The measurements are the Gospel of Jesus Christ that allows “the glory of God to come in,” Ezek 43:2.
measure the temple of God and the altar – here John measures the sanctified Church, the true Church according to the measurements of Gospel of Christ, and counts those who are true.
