'Measuring rod' in the Bible

And there was given to me a measuring rod: and one said, Go up and take the measure of the house of God, and the altar, and the worshippers 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.

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.
