1 Kings 6:31

Corners, each piece being, perhaps, a cubit in length, so that the two folding-doors would contain ten cubits, or half the wall. But Ezechiel only assigns six cubits to this door, and ten to that of which opened into the holy place. Hebrew, "the lintel and the side posts, a fifth" of the wall; in which sense, the door must not have been above four cubits. So ver. 33, four-square is translated also, "a fourth part." But it does not appear to what it refers. Rebihith sometimes means four-square; and why may not chamishith here signify pentagonal? (Calmet) --- Many suppose that the gate of the sanctuary was of this form, (Haydock) ending in a point at the top; unless the posts were carved so as to have five angles, like a pillar. (Ribera, Templ. ii. 8.) (Menochius)
