וַהֲסִבּוֹתִ֤י פָנַי֙ מֵהֶ֔ם וְחִלְּל֖וּ אֶת־צְפוּנִ֑י וּבָאוּ־בָ֥הּ פָּרִיצִ֖ים וְחִלְּלֽוּהָ׃ (פ)
我必轉臉不顧他們；他們必褻瀆我隱密之處，強暴的人必進入其中，褻瀆那地方。
Rabbeinu Bahya
פנו לכם צפונה, “turn yourselves northward!” Devarim Rabbah 1,19 comments on this that when the time arrives for Esau to be supreme, it behooves Israel to move north. Another comment from the Midrash: G’d said: “I have only one Altar and he (Esau) is going to destroy it.” [It is seen as a concealed warning not to make common cause with the people who in the end will destroy the Temple. The Israelites (Hyrcan and Antipater) who called in the Romans for political reasons lived to suffer the consequences. The word צפון is understood as something hidden, exclusive; in other words: “do not share your exclusive and direct ‘hotline’ to G’d.” Ed.]
