Ezekiel 40:3-5

New Revised Standard Version, Anglicised

³ When he brought me there, a man was there, whose appearance shone like bronze, with a linen cord and a measuring reed in his hand; and he was standing in the gateway. ⁴ The man said to me, ‘Mortal, look closely and listen attentively, and set your mind upon all that I shall show you, for you were brought here in order that I might show it to you; declare all that you see to the house of Israel.’

⁵ Now there was a wall all round the outside of the temple area. The length of the measuring reed in the man’s hand was six long cubits, each being a cubit and a handbreadth in length; so he measured the thickness of the wall, one reed; and the height, one reed.
