'Measuring rod' in the Bible

And he brought me there, and, behold, there was a man, whose appearance was like the appearance of bronze, with a line of flax in his hand, and a measuring rod; and he stood in the gate.

And behold a wall on the outside of the house round about, and in the man's hand a measuring rod of six cubits long by the cubit and a handbreadth: so he measured the width of the building, one rod; and the height, one rod.

He measured the east side with the measuring rod, five hundred rods, with the measuring rod all around.

He measured the north side, five hundred rods, with the measuring rod all around.

He measured the south side, five hundred rods, with the measuring rod.

He turned about to the west side, and measured five hundred rods with the measuring rod.
