Charles Ellicott Commentary Ezekiel 43:11

"And if they be ashamed of all that they have done, make known unto them the form of the house, and the fashion thereof, and the egresses thereof, and the entrances thereof, and all the forms thereof, and all the ordinances thereof, and all the forms thereof, and all the laws thereof; and write it in their sight; that they may keep the whole form thereof, and all the ordinances thereof, and do them." — Ezekiel 43:11 (ASV)

If they are ashamed.— The same thing that had already been declared positively is now expressed contingently, showing that the sanctification of the people and God’s dwelling among them were correlative facts; the one could not be without the other. Many expressions of nearly the same meaning are heaped up, as it were, in the latter part of this verse, to emphasize the significance of the arrangements of the new Temple, and to secure the people's thought and consideration for them.
