Rabbeinu Bahya
ואתחנן אל ה' בעת ההיא לאמור, “I pleaded with the Lord at that time, saying:” the words בעת ההיא, “at that time,” refer to the aftermath of the defeat of Sichon and Og, whose lands were given to the Israelites. At that time Moses had dared hope that maybe the decree that he would not be allowed to enter the Holy Land had been canceled. This verse is a continuation of verse 21 when the Torah mentioned ”these two kings.”
