nkjv@Ezekiel:41:6 @ The side chambers were in three stories, one above the other, thirty chambers in each story; they rested on ledges which were for the side chambers all around, that they might be supported, but not fastened to the wall of the temple.

nkjv@Ezekiel:41:7 @ As one went up from story to story, the side chambers became wider all around, because their supporting ledges in the wall of the temple ascended like steps; therefore the width of the structure increased as one went up from the lowest story to the highest by way of the middle one.
