Ezekiel 40:3-6

3He took me there, and I saw a man whose appearance was like bronze; he was standing in the gateway with a linen cord and a measuring rod in his hand.

4The man said to me, “Son of man, look carefully and listen closely and pay attention to everything I am going to show you, for that is why you have been brought here. Tell the people of Israel everything you see.”

5I saw a wall completely surrounding the temple area. The length of the measuring rod in the man’s hand was six long cubits, each of which was a cubit and a handbreadth. He measured the wall; it was one measuring rod thick and one rod high.

6Then he went to the east gate. He climbed its steps and measured the threshold of the gate; it was one rod deep.
