Ezekiel 40:3

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.

Behold, there was a man. The Old Testament manifestations of heavenly beings as men prepared men's minds for the coming incarnation.

Whose appearance was like the appearance of brass - resplendent.

With a line of flax in his hand - used for longer measurements (, "Behold, a man with a measuring line in his hand ").

Reed - used in measuring houses (). It marked the straightness of the walls.
