The Heichal [measured] one hundred [amos] by one hundred [amos] with a height of one hundred [amos]: the Otem [was] six amos, the height of [the Heichal was] forty amos, one amah [was for the] decoration, two amos [for the] bracing, one amah [for the] ceiling, one amah [for the] pavement; and the height of the upper story [was] forty amos, one amah [was for the] decoration, two amos [for the] bracing, one amah [for the] ceiling, one amah [for the] pavement, three amos [for the] fence, and one amah [for the] “crow-chaser.” R’ Yehudah says: The “crow-chaser” was not included in the measure [of 100 amos]; rather, four amos was [the height of the] fence.
