@af86ac1d: In the book of Revelation, there is a similar image of a man with a measuring rod. In Revelation 11:1-2, John sees a vision of a man who is measuring the temple of God. The man is instructed to measure the temple, but not the outer court, which has been given over to the Gentiles. The image of the man with the measuring rod is often seen as representing God's plan for the restoration of the temple and the renewal of worship in the end times.
The measuring rod symbolizes God's authority and sovereignty over the temple and the worship that takes place there. The fact that the outer court is not measured may symbolize the fact that it has been given over to the Gentiles, who represent the forces of evil and opposition to God. The image of the man with the measuring rod may also be seen as a symbol of the final judgment, in which God will measure and evaluate the faithfulness of his people.
Overall, the image of the man with the measuring rod in Revelation is similar to the image of the man with the measuring line in Zechariah, and both images are seen as representing God's plan for the restoration and renewal of his people.
