Ezekiel 40:36-38

Young's Literal Translation

³⁶ its little chambers, its posts, and its arches; and windows [are] to it all round about: the length fifty cubits, and the breadth five and twenty cubits;

³⁷ and its posts [are] to the outer court, and palm-trees [are] unto its posts, on this side and on that side, and eight steps [are] its ascent.

³⁸ And the chamber and its opening [is] by the posts of the gates, there they purge the burnt-offering.
