Ezekiel 40:3

Then he brought me to the nave and measured the side pillars; six cubits wide on each side was the width of the side pillar.

He measured on the east side with the measuring reed 500 reeds by the measuring reed.

Then I heard one speaking to me from the house, while a man was standing beside me.

Then I lifted up my eyes and saw, and behold, there was a man with a measuring cord in his hand.

So I said, “Where are you going?” And he said to me, “To measure Jerusalem, to see how wide it is and how long it is.”

Then a measuring rod like a staff was given to me, saying, “Get up and measure the sanctuary of God and the altar, and those who worship in it.

And the one who spoke with me had a gold measuring rod to measure the city and its gates and its wall.
