And three amohs was its height. The height of the base excluding the height of the wheel (meaning: excluding the base [=כן] itself; יד האופן is the wheel) upon which it rests was an amoh and a half, and the height of the base was an amoh and a half. (Four amohs was the length, etc.) The amoh of the height was square but the half amoh was round, as it is stated, “At the top of the base [was a frame] half an amoh high circular all around.”47Below v. 35.
