Matthew Poole and continuators on Ezekiel 42:15

15 Now when he had made an end of measuring the inner house , he brought me forth toward the gate, whose prospect is toward the east , and measured it round about .

The Holy of Holies, the Temple, and all the buildings, that were in it, and its inner Courts.

Quite out to the outmost Court, and Wall of it, which compassed all the rest of the Courts.

To the East gate of the outside Wall, mention'd chap. 40. verse 5. which see at let. i. and k.

i. e. The four squares of the wall for this, as the other walls, was square, not round, and therefore this round about is to be understood of measuring all four equilateral sides or parallels.
