Midrasz do Liczb 24:19

Rabbi Yehoshua ben Levi said: If the nations had known how beneficial the Tent of Meeting was for them, they would have surrounded it [to protect it] with military encampments and fortifications, as until the Tent of Meeting stood, they would hear the sound of divine speech, and would lose control of their bowels in the halls of their palaces.⁴⁴Many of them lost control of their faculties and even died due to the fear and trepidation involved in hearing the divine speech. That is what is written: “For who of all flesh who heard the voice of the living God… [has lived?]” (Deuteronomy 5:23). Rabbi Simon said: The divine speech would emerge in two forms; an elixir of life for Israel and an elixir of death for the nations of the world. An elixir of life for Israel, “[Has a people heard the voice of God speaking…] as you heard, and lived?” (Deuteronomy 4:33); you heard and lived. And an elixir of death for the nations of the world, they heard and died. Therefore it says: “Under the apple tree I roused you” (Song of Songs 8:5).⁴⁵The apple tree is understood here as an allusion to Mount Sinai (Maharzu). The verse indicates that God roused Israel from the dead after speaking to them, whereas He did not rouse the nations of the world who heard Him speak (Etz Yosef).
“[The Lord called to Moses, and spoke to him] from the Tent of Meeting” (Leviticus 1:1). Rabbi Ḥiyya taught that from there the voice would stop and would not emerge outside the tent. Rabbi Yitzḥak said: Before the Tent of Meeting stood, prophecy was found among the nations of the world. Once the Tent of Meeting stood, prophecy ceased from them. From there, “I grasped him and I would not release him” (Song of Songs 3:4).⁴⁶This is expounded in reference to prophecy. If you say: But did Bilam ben Beor not prophesy? Say, it was for the benefit of Israel that he prophesied, as it is stated: “How goodly are your tents, Jacob” (Numbers 24:5); “one has seen no iniquity in Jacob” (Numbers 23:21); “for there is no divination in Jacob” (Numbers 23:23); “who has counted the dust of Jacob” (Numbers 23:10); “a star has risen from Jacob” (Numbers 24:17); “one from Jacob will rule” (Numbers 24:19).

Jacob took all the tithe of his possessions and sent it by the hand of his servants, and gave it to Esau, saying to them: Say ye || to him, "Thus saith thy servant Jacob" (Gen. 32:4). The Holy One, blessed be He, said to him: Jacob ! That which was holy hast thou made profane? He replied to Him: Sovereign of all worlds ! I flatter the wicked, so that he should not slay me. Hence the (wise men) say, we may flatter the wicked in this world for the sake of the ways of peace. Esau said to him: O my brother, I have enough; as it is said, "And Esau said, I have enough" (Gen. 33:9). And because he gave honour to Jacob, therefore the sons of Jacob paid honour to the sons of Esau with the same expression; as it is said, "Ye have compassed this mountain long enough" (Deut. 2:8). The Holy One, blessed be He, said to him: Jacob ! Is it not enough for thee that thou hast made profane that which is holy? Nay, but I have said, "And the elder shall serve the younger" (Gen. 25:23); and yet thou hast said, "Thy servant Jacob" (Gen. 32:4). By thy life ! it shall be according to thy words; he shall rule over thee in this world, and thou shalt rule over him in the world to come. Therefore Jacob said to him (Esau): "Let my lord, I pray thee, pass over before his servant" (Gen. 33:14). Hence thou mayest learn that the sons of Esau will not fall until a remnant from Jacob shall come, and cut off the feet of the children of Esau from Mount Seir, and the Holy One, blessed be He, will descend. "And there shall not be any remaining to the house of Esau; for the Lord hath spoken it" (Obad. 18).

Another explanation. “I held him and would not let him go…” R’ Yitzchak said: until the Tabernacle was erected prophecy was found among the idol worshipers. Once the Tabernacle was erected it was removed from them, as it says “I held him and would not let him go…” and it is written “Then I and Your people will be distinguished…” (Exodus 33:16) They said to him: but Balaam had prophecy? He replied: Not for his benefit! “Who counted the dust of Jacob…” (Bamidbar 23:10) “He does not look at evil in Jacob…” (Bamidbar 23:21) “How goodly are your tents, O Jacob…” (Bamidbar 25:4) “A star has gone forth from Jacob…” (Bamidbar 24:17) “A ruler shall come out of Jacob…” (Bamidbar 24:19) Another explanation. “On my bed at night…” (Song of Songs 3:1) Because I rested from Torah and commandments, night was joined to night for me. In the past it illuminated for me between night and night, between the night of Egypt and the night of Bavel, but now night is joined to night.
