Ezekiel 40:21-23

Young's Literal Translation

²¹ and its little chambers, three on this side, and three on that side, and its posts and its arches have been according to the measure of the first gate, fifty cubits its length, and the breadth five and twenty by the cubit;

²² and its windows, and its arches, and its palm-trees [are] according to the measure of the gate whose face [is] eastward, and by seven steps they go up on it, and its arches [are] before them.

²³ And the gate of the inner court [is] over-against the gate at the north and at the east; and he measureth from gate unto gate, a hundred cubits.
