Midrash for Numbers 23:23

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).

Ahaba the son of R. Zera was taught: Whoever does not practice sorcery will be brought into an abode where even the ministering angels will not be able to approach, as it is said (Num. 23, 23) for there is no enchantment in Jacob, etc. At the proper time shall it be said to Jacob and Israel what God doth work.

R. Tanhuma opened < his discourse > (with Job 41:3 [11]): WHO HAS ADVANCED ME ANYTHING? I SHALL REPAY HIM. EVERYTHING UNDER THE HEAVENS IS MINE.⁴⁹Tanh., Lev. 8:7; Lev. R. 27:2; PRK 9:2. This refers to a bachelor who dwells in a province and gives an allowance to Bible and Mishnah teachers.⁵⁰In elementary school one studied Bible under a sopher, or scribe. Secondary school involved the study of Oral Torah. Since a bachelor has no children, the money he gives is an act of charity. The Holy One said: It is for me to pay him the compensation of a male child. R. Jeremiah bar Eleazar said: There is going to be a heavenly voice (bat qol) that shall explode on the tops of the mountains and say: Whoever has done < something > along with God, let him come and receive his reward. [This is what is written (in Numb. 23:23): NOW (in the age to come) IT IS SAID FOR JACOB AND FOR ISRAEL: WHAT HAS GOD DONE?] The Holy Spirit also proclaims (in Job 41:3 [11]): WHO HAS ADVANCED ME ANYTHING? I WILL REPAY HIM. Who offered me praise⁵¹Qilles. Cf. the Greek, kalos (“beautiful”). before I gave him breath? Who has performed circumcision for me before I gave him a male child? Who made a tassel for me before I gave him a prayer shawl? Who made a parapet (in accord with Deut. 22:8) for me [before I gave him a roof? Who made a mezuzah] before I gave him a house? Who made a sukkah for me before I gave him room? Who set aside pe'ah before I gave him a field? Who set aside grain offering and tithe before I gave him a threshing floor? Who set aside first fruits, tithes, and sacrifice before I gave him cattle? [This is what is written] (in Lev. 22:27): WHEN A BULL OR A SHEEP OR A GOAT < IS BORN…. >
