Kommentar zu Dewarim 1:20

ואומר אליכם, באתם עד הר האמרי, “and I said to you: you have arrived at the Mountain of the Emorite;” here Moses refers to what has been written in Numbers 13,17: עלו זה בנגב ועליתם את ההר, “ascend here in the south and climb the mountain!” it also says there in chapter 14,40: וישכימו בבקר ויעלו על ראש ההר, “they arose early in the morning and ascended the top of the mountain.”
