'Measuring rod' in the Bible

Then a measuring rod like a staff was given to me, and I was told, "Get up and measure the temple of God, and the altar, and the ones who worship there.

The angel who spoke to me had a golden measuring rod with which to measure the city and its foundation stones and wall.

Now the city is laid out as a square, its length and width the same. He measured the city with the measuring rod at fourteen hundred miles (its length and width and height are equal).
