Tafsiran Ulangan 2:3: Rashi, Chizkuni, Da'at Zekenim & Kli Yakar

פנו לכם צפנה TURN YOU NORTHWARD — Turn you along the eastern side of Moab, from the south to the north, your faces directed to the north. Consequently they were travelling along the east side of Moab, and this is what is meant by (Judges 11:18) “And they came by the east side of the land of Moab”.

ההר הזה, “this mountain.” This is Mount Seir.

רב לכם, סוב, “you have been skirting this land enough, now turn around (in a northerly direction) The word רב here is used in the same way as Esau used it in his encounter with Yaakov in Genesis 33,9 when he first wanted to refuse to accept Yaakov’s gift and said to him:יש לי רב אחי “I have lots, my brother;” he meant that he had been repaid sufficiently for any harm Yaakov had caused him in the past.
