'Measuring rod' in the Bible

And a measuring rod similar in appearance to a staff was given to me, saying, "Get up and measure the temple of God and the altar and those who worship in it.

And the one who spoke with me was holding a golden measuring rod in order that he could measure the city and its gates and its wall.

And the city is laid out as a square, and its length is the same as [its] width. And he measured the city with the measuring rod at twelve thousand stadia; the length and the width and the height of it are equal.
