Комментарий к Дварим 4:47

אשר בעבר הירדן WHO WERE BEYOND THE JORDAN — On the east side of Jordan, because the other side was on the west. [This means on the side opposite the western side.]

He mentioned here and they took his [Sihon’s] land in possession, and the land of Og king of Bashan etc. from Aroer etc.¹²¹Verses 47-48. the sense of it being that he reverted to what he had stated at the beginning of this book, that the explanation of this Torah was [given] after he had smitten Sihon etc.,¹²²Above, 1:4. and he further explained here that this expounding of the Torah was also after they took all their lands [of Sihon and Og] in possession, that is, after he divided them among the two and a half tribes [Gad, Reuben, and the half-tribe of Menasheh].

ויירשו את ארצו, they inherited his country after having conquered land that had been inhabited, suitable for settlement. This land would offer the opportunity to observe all of G’d’s commandments in it. They would not need to fear invaders, etc. This is where Moses began his review of the Torah and his speech of warning the people of the importance of remaining loyal to G’d.

ויירשו את ארצו ואת ארץ עוג מלך הבשן, “they inherited his land as well as the land of Og, King of Bashan.” Seeing that Moses reverted back to what he had been speaking about at the beginning of his review of the Torah, a review occasioned by the successful campaign against Sichon and Og, this subject is touched upon again to show that Moses continued with his discourse explaining the Torah.
