Ezekiel 40:3-6

3So He brought me there; and behold, there was a man [an angel] whose appearance was like bronze, with a line of flax and a measuring rod in his hand; and he was standing in the gateway.

4The man said to me, “Son of man, look with your eyes and hear with your ears and set your heart on all that I am going to show you; for you have been brought here that I may show it to you. Declare to the house of Israel all that you see.”

5And behold, there was a wall all around the outside [area] of the temple (house) [of the Lord], and in the man’s hand a measuring rod six cubits long (10.2 ft.), each cubit being longer than the standard one by a hand width. So he measured the thickness of the wall, one rod; and the height, one rod.

6Then he went to the gate which faced the east and went up its [seven] steps and measured the threshold of the gate, one rod in width; and the other threshold [of the gate inside the thick wall] was one rod in width.
