'Four sided' in the Bible

Solomon also provided four-sided doorposts made of cypress wood for the entrance to the outer sanctuary,

All of the doorways and the doorframes [had] four-sided casings, with opening to opposite opening three times.

Its opening from [the] inside of the capital and above [was] a cubit; its pedestal [was] a round work of a cubit and a half; moreover, on its opening [were] the carvings with four-sided frames, not circular.
