KJV:

3 And he brought me thither, and, behold, there was a man, whose appearance was like the appearance of brass, with a line of flax in his hand, and a measuring reed; and he stood in the gate.
4 And the man said unto me, Son of man, behold with thine eyes, and hear with thine ears, and set thine heart upon all that I shall shew thee; for to the intent that I might shew them unto thee art thou brought hither: declare all that thou seest to the house of Israel.

5 And behold a wall on the outside of the house round about, and in the man's hand a measuring reed of six cubits long by the cubit and an hand breadth: so he measured the breadth of the building, one reed; and the height, one reed.

NASB:

3 So He brought me there; and behold, there was a man whose appearance was like the appearance of bronze, with a line of flax and a measuring rod in his hand; and he was standing in the gateway.
4 The man said to me, " Son of man, see with your eyes, hear with your ears, and give attention to all that I am going to show you; for you have been brought here in order to show it to you. Declare to the house of Israel all that you see."
5 And behold, there was a wall on the outside of the temple all around, and in the man's hand was a measuring rod of six cubits, each of which was a cubit and a handbreadth. So he measured the thickness of the wall, one rod; and the height, one rod.
