Ezekiel 40:27

He led me toward the south; and behold, there was a gate toward the south. He measured its posts and its arches according to these measurements.

There were windows in it and in its arches all around, like the other windows: the length was fifty cubits, and the width twenty-five cubits.

There were seven steps to go up to it, and its arches were before them. It had palm trees, one on this side, and another on that side, on its posts.

Then he brought me to the inner court by the south gate. He measured the south gate according to these measurements;

with its lodges, its posts, and its arches, according to these measurements. There were windows in it and in its arches all around. It was fifty cubits long, and twenty-five cubits wide.

There were arches all around, twenty-five cubits long and five cubits wide.
