'Measuring reed' in the Bible

And he brought me thither, and behold, there was a man whose appearance was like the appearance of brass, with a flax-cord in his hand, and a measuring-reed; and he stood in the gate.

And behold, there was a wall on the outside of the house round about, and in the man's hand a measuring-reed of six cubits, each of one cubit and a hand breadth. And he measured the breadth of the building, one reed; and the height, one reed.

He measured the east side with the measuring-reed, five hundred reeds, with the measuring-reed round about.

He measured the north side, five hundred reeds, with the measuring-reed round about.

He measured the south side, five hundred reeds, with the measuring-reed.

He turned about to the west side, and measured five hundred reeds with the measuring-reed.
