Jezekiel 41:8 In-Context

6 And the sides were twice ninety, side against side; and a space in the wall of the house at the sides round about, that they should be for them that take hold of them to see, that they should not at all touch the walls of the house.
7 And the breadth of the upper side according to the projection out of the wall, against the upper one round about the house, that it might be enlarged above, and that might go up to the upper chambers from those below, and from the ground-sills to the third story.
8 And as for the height of the house round about, space between the sides was equal to a reed of six cubits;
9 and the breadth of the wall of each side without was five cubits; and the spaces that were left between the sides of the house,
10 and between the chambers, were a width of twenty cubits, the circumference of the house.
