John Gill Commentary 1 Kings 6:33

"So also made he for the entrance of the temple door-posts of olive-wood, out of a fourth part [of the wall];" — 1 Kings 6:33 (ASV)

So also made he for the door of the temple
The holy place:

posts [of] olive tree, a fourth part [of the wall] ; which was five cubits, its breadth being twenty, (1 Kings 6:20); this door was a cubit wider than that into the most holy place, (1 Kings 6:31), more entering into the one than into the other; as more go into the church on earth than into the heavenly glory.
