"And your foes will dissimulate to you" (in fear of you): When Israel was prospering, the Babylonians dissimulated to them, deporting themselves like brothers, as Esav spoke to Jacob (Bereshith 33:9) "My brother, let there be yours what is yours," and as Chiram to Solomon, (I Kings 9:13) "What are these cities that you have given me, my brother?"
"and you will tread on their high places": as in (Joshua 10:24) "And Joshua called to all the men of Israel and said to the officers, etc."
(Devarim 34:1) "And Moses went up from the plains of Moav": It was an ascent for him and not a descent.
