Midrash su Salmi 132:6

[“Benjamin is a wolf, he will prey…” (Bereshit 49:27)] “Why do you lurk, you lofty mountains, for the mountain that God desired for His dwelling?” (Tehillim 68:17) R’ Yosi haGalili and R’ Akiva: R’ Yosi haGalili explained the verse as referring to the mountains. At the moment when the Holy One came to give the Torah on Sinai the mountains came running and arguing with each other. This one said ‘the Torah will be given on me!’ and this one said ‘the Torah will be given on me!’ Mount Tabor came from Bet Elim and Mount Carmel from Espamia, this is what is written “As long as I live, says the King, Whose name is the Lord of Hosts, that as sure as Tabor is among the mountains, and Carmel is by the sea, it shall come about.” (Yimiyahu 46:18) This one said ‘I was called!’ and this one said ‘I was called!’ The Holy One said ‘Why do you lurk, you lofty mountains?’ You are all high mountains, but what does lofty (gavnunim) mean? As it says “…or one with long eyebrows (gibein), or a cataract…” (Vayikra 21:20) Idolatry was done on all of you, but Sinai upon which idolatry was never done “…the mountain that God desired for His dwelling,” (Tehillim 68:17) “The Lord descended upon Mount Sinai…” (Shemot 19:20) Nevertheless, “…Even the Lord will dwell [there] forever,” (Tehillim 68:17) refers to the eternal House. R’ Akiva explained the verse as referring to the tribes. At the moment when Shlomo said to build the Holy Temple, the tribes came running and arguing with each other. This one said ‘in my portion it will be built!’ This one said ‘in my portion it will be built!’ The Holy One said to them ‘tribes, why are you lurking? All of you are tribes, all of you are righteous – but lofty (gavnunim). What is gavnunim? Ganavim (thieves). You were all partners in the sale of Yosef; but Benyamin, who did not participate in the sale of Yosef, “…the mountain that God desired for His dwelling.” (Tehillim 68:17) So we find that four hundred and eighty years beforehand the children of Korach prophesied on this, that in the future it would be in the portion of Benyamin as it says “My soul yearns, yea, it pines for the courts of the Lord…” (Tehillim 84:3) So too it says “Behold we heard it in Ephrath…” (Tehillim 132:6) R’ Yehudah says ‘the Holy Temple was built in the portion of Yehudah, as it is written “…Ephrathite man from Bethlehem of Judah…”’ (Shmuel I 17:12) R’ Shimon says ‘in the portion of the son of she who died in Ephrathah. And who died in Ephrathah? Rachel. Perhaps it was in the portion of Yosef who is also among her sons? The verse says “…we found it in the fields of the forest.” (Tehillim 132:6) In the portion of the one who is compared to a beast of the forest, and who is so compared? Benyamin, as it is written “Benjamin is a wolf, he will prey…” (Bereshit 49:27)

R. Meir says: She died in the portion of Benjamin, her son, as it is written (Ibid. 48:7) "for when I came from Paden, Rachel died upon me … before Efrath, etc." And Efrath is none other than Bethlehem, viz. (Michah 5:1) "And you, Bethlehem, Efrathah." I might think, in the portion of Joseph, her son; it is, therefore, written (Psalms 132:6) "Behold, we heard of it in Efrath; we found it in the field of the forest" — with him who is compared to an animal of the forest. And who is that? Benjamin, as it is written (Bereshith 49:27) "Benjamin is a wolf that will tear."
