Ezekiel 41:1,2

Afterward he brought me to the temple “After having described the courts and the porch, the prophet enters into the temple, properly so called, whereof he gives the dimensions and description.” And he measured the posts By the posts are meant the door-cases on each side of the entrance. These were six cubits thick on the north and south sides; which was the breadth of the tabernacle These walls, in their thickness, took up as much space as the whole breadth of Moses's tabernacle, as appears from Exodus 26:16; Exodus 26:22; where the west side of the tabernacle consists of eight boards, each a cubit and a half broad. The breadth of the door was ten cubits, &c. The entrance itself being ten cubits broad, and the wall on each side five cubits, makes the breadth of the house to be just twenty cubits, as it is expressed in the latter part of the verse, which was the same in Solomon's temple, 1 Kings 6:2. And the length forty cubits Namely, the length of the first sanctuary, or holy place, as distinct from the holy of holies, which was twenty cubits in length, Ezekiel 41:4, and made the whole structure sixty cubits long; wherein it agreed with Solomon's temple.
