Midrash su Numeri 22:5

“The adversary extended his hand over all her delights; for she saw the nations entering her Sanctuary, whom You had commanded that they should not enter Your assembly” (Lamentations 1:10).
“The adversary extended his hand.” You find that when the enemies entered the Temple, Amonites and Moavites entered with them. Everyone was running to plunder silver and gold, and the Amonites and Moavites were running to plunder the Torah, in order to remove “An Amonite and Moavite shall not enter the assembly of the Lord” (Deuteronomy 23:4). Rabbi Yehuda ben Rabbi Simon [said] in the name of Rabbi Levi ben Perata: This is analogous to a conflagration that was ignited in a king’s palace. Everyone was running to plunder the silver and the gold while a slave ran to plunder his writ of servitude. So too, when the enemies entered the Temple, Amonites and Moavites entered with them. Everyone was running to plunder silver and gold, and the Amonites and Moavites were running to plunder the Torah, in order to remove “An Amonite and Moavite shall not enter the assembly of the Lord.”
Abraham bestowed four good things upon Lot. That is what is written: “Abram went, as the Lord had spoken to him, and Lot went with him” (Genesis 12:4). And it says: “Lot, too, who was going with Abram [had sheep, cattle and tents]” (Genesis 13:5). And it says: “He returned all the property, [and also his brother Lot and his property he returned]” (Genesis 14:16). And it says: “It was when God destroyed the cities of the plain [God remembered Abraham, and He sent Lot from the midst of the upheaval]” (Genesis 19:29). Correspondingly, they should have repaid them with goodness;¹⁴³Lot’s descendants, the nations of Amon and Moav, should have been kind to Abraham’s descendants. however, they performed acts of wickedness. That is what is written: “He sent messengers to Bilam…now, please go and curse for me…. The elders of Moav and the elders of Midian went…” (Numbers 22:5–7). “He gathered to him the children of Amon and Amalek, [and he went and smote Israel]” (Judges 3:13).¹⁴⁴The verse is stated regarding Eglon, king of Moav. “It was thereafter, the children of Moav, and the children of Amon, and with them some Amonites, came against Yehoshafat” (II Chronicles 20:1). And this: “The adversary extended his hand...”
Correspondingly, their sins are written in four places. “An Amonite and Moavite [shall not enter the assembly of the Lord]…because they did not greet you with bread and with water…” (Deuteronomy 23:4–5). “My people, remember now what Balak king of Moav devised…” (Micah 6:5). “Because they did not greet the children of Israel with bread and with water, and hired Bilam against them, to curse them” (Nehemiah 13:2). “He sent and summoned Bilam son of Beor to curse you” (Joshua 24:9).
Correspondingly, four prophets stood and sealed their sentence, and they were: Isaiah, Jeremiah, Ezekiel, and Zephaniah. Isaiah said: “A prophecy of Moav: For on the night that Ar of Moav is plundered, it is ruined; for on the night that Kir of Moav is plundered, it is ruined” (Isaiah 15:1). Jeremiah said: “Behold, days are coming, the utterance of the Lord, and I will sound to Raba of the children of Amon an alarm of war, and it will become a mound of desolation, and its environs will be burned in fire, and Israel will inherit its inheritors, said the Lord” (Jeremiah 49:2). Ezekiel said: “To the children of the east, against the children of Amon, and I will give it as a heritage, so that the children of Amon will not be remembered among the nations. I will administer punishments to Moav, and they will know that I am the Lord” (Ezekiel 25:10–11). Zephaniah said: “Therefore, as I live, the utterance of the Lord of hosts, God of Israel, Moav will be like Sodom and the children of Amon like Gomorrah, a rustling thornbush, a salt mine, a desolate wasteland forever. The remnant of My people will plunder them and the rest of My nation will inherit them” (Zephaniah 2:9).

7) "and he shall pinch its head opposite (mul) its nape": opposite the beholder of the nape, as it is written (Numbers 22:5): "and it abides opposite (mul) me." "but he shall not sunder (it)": i.e., he shall pinch only one (shechitah) sign and not more. If he does it is unfit.

8) "And he shall sprinkle from the blood of the sin-offering": from the body of the sin-offering (and not from a vessel). "upon the wall of the altar": not upon the wall of the ramp, and not upon the wall of the heichal (the hall containing the altar), but upon the lower wall (under the red line). It would (seem to) follow: Now if a beast, whose burnt-offering is below, its sin-offering is above — a bird, whose burnt-offering is above, should it not follow that its sin-offering is above? It is, therefore, (to negate this) written (Numbers 22:5): "and what remains of the blood shall be drained out at the base of the altar, (the wall from which) the left-overs of the blood are drained to the foundation — the bottom wall.
