Ezekiel 42:15-20 - Outside Dimensions Of The Temple Complex
15 And he hath finished the measurements of the inner house, and hath brought me forth the way of the gate whose front is eastward, and he hath measured it all round about.
16 He hath measured the east side with the measuring-reed, five hundred reeds, with the measuring-reed round about. 17 He hath measured the north side, five hundred reeds, with the measuring reed round about. 18 The south side he hath measured, five hundred reeds, with the measuring-reed. 19 He hath turned round unto the west side, he hath measured five hundred reeds with the measuring-reed.
20 At the four sides he hath measured it, a wall is to it all round about, the length five hundred, and the breadth five hundred, to separate between the holy and the profane place.
