'Measuring rod' in the Bible

Then a reed was given me to serve as a measuring rod; and a voice said, "Rise, and measure God's sanctuary--and the altar--and count the worshipers who are in it.

Now he who was speaking to me had a measuring-rod of gold, with which to measure the city and its gates and its wall.

The plan of the city is a square, the length being the same as the breadth; and he measured the city furlong by furlong, with his measuring rod--it is twelve hundred miles long, and the length and the breadth and the height of it are equal.
