פּירוש אויף דברים 2:37

כל יד נחל יבק means, ALL THE DISTRICT BESIDE THE BROOK OF JABBOK.

רק אל ארץ בני עמון לא קרבת, “only to the land of the Bney Ammon did you not come close;” according to Ibn Ezra Moses speaks only of land that was in possession of that nation at the time he spoke. This excluded the land captured from Sichon, which at one time did belong to the Bney Ammon, but which would not be returned to them by the Israelites who had taken it away from Sichon.

the land of the Children of Ammon i.e., the land that presently remains in their hands, as I have explained [comment on Numbers 21: 24].

וכל אשר צוה ה' אלהינו לנו — This means, AND ALL WHICH THE LORD OUR GOD COMMANDED US not to capture, we left.
