Chasidut su Genesi 12:20

And Yaakov sent messengers ahead of him (Gen. 32:4) - this is explained in the way of hint [remez]. Behold the work of the tzadik is to be clinging to the Blessed and Elevated One, to cling his soul under the Throne of Glory, the place of his root, and the tzadik purifies and cleanses himself from all external desires - and then his cleansed body too clings to the Blessed One. And this is the expression "tefilah" [prayer], that is, clinging, like "the wrestlings [naftulei] of Elokim etc" (Gen. 30:8) [meaning] that the tzadik clings to the Blessed One through the clear and lucid prayers from/in pure thoughts. And this is "and he sent", an expression of accompanying [levayah] as in "Pharaoh commanded men and they accompanied him" (Gen. 12:20), and the Targum: "they led him" [v'a'l'viy'u] (Targum Jonathan on Genesis 12:20), meaning that the tzadik accompanies the messengers that go before him, that is, the words that come out of the mouth of the tzadik create angels from themselves, and the same happens with his clean body which helps his angels to go upward, "ahead of him to Esav his brother"- meaning, through this he causes Esac to become his brother. "Towards the land of Seir" - meaning, that he becomes his brother on below, this is the hint of "field of Edom", the angel-deputy of Edom also becomes his brother.
