Midrash sobre Números 22:21

(Exodus 14:6) "And he harnessed his chariot": He himself. It is the way of kings to stand while other equip their chariot and harness it, but here the wicked Pharaoh himself harnessed and equipped it. And when the Egyptian nobles saw this, all of them arose and did the same. Four "harnessed" with joy: Abraham — (Genesis 22:3) "And Abraham rose early in the morning (for the binding of Isaac), and he saddled his ass." Now did he not have many servants? __ (He did so) for the honor of the L rd. Joseph — (Ibid. 46:29) "and Joseph (himself) harnessed his chariot." Did he not have many servants? — (He did so) in honor of his father. Bilam — (Numbers 22:21) "And Bilam arose in the morning and (himself) saddled his ass" (to go with the emissaries of Balak.) Pharaoh — here. Let the "saddling" of Abraham come, who went to do the will of the L rd and oppose the "saddling" of Bilam, who went to curse Israel. Let the "harnessing" of Joseph come and oppose the "harnessing" of the wicked Pharaoh, who went to pursue Israel. Variantly: R. Shimon b. Yochai says: Let the hand-sword of Abraham come — (Genesis 22:10) "And he took the knife to slaughter his son" — and oppose the hand-sword wielded by the wicked Pharaoh in pursuing Israel — (Exodus 15:9) "I shall draw forth my sword; my hand will impoverish them."

(Ib. b) (Num. 22, 21) And Balaam rose up in the morning and saddled his ass." We are taught in a Baraitha in the name of R. Simon b. Elazar: "Love disregards the rule of dignified conduct and causes men to do things ordinarily left to servants, as we have seen by Abraham, concerning whom it is written (Gen. 22, 3) And Abraham rose early in the morning and saddled his ass [because of his love for the Creator]; so does hatred disregard the rule of dignified conduct. We learn it from Bil'am concerning whom the passage says And Bil'am rose up in the morning, and saddled his ass, [because of his animosity for Israel]."

12 (Numb. 22:20) “Then God came unto Balaam at night”: This text is related (to Exod. 12:42), “That was for the Lord a night of vigil […].” All miracles which were done for Israel and which involved exacting retribution for them from the wicked took place at night: (Gen. 31:24) “And God came unto Laban the Aramean in a dream at night”: And it is written (in Gen. 20:3), “But God came unto Abimelech in a dream at night.” And it is written (in Exod. 12:29), “And it came to pass in the middle of the night.” And it is written (in Exod. 14:20), “there was the cloud with the darkness, and it cast a spell upon the night.” And it is written (in Gen. 14:15), “And he deployed at night.” And so [it was with] all of them. Another interpretation: Why did he reveal himself to Balaam by night? He was not worthy of [receiving] the holy spirit [except at night]. As He speaks at night with all the prophets of the nations, as stated (in Job 4:13), “In opinions from night visions.” And so Eliphaz says (in Job 4:13), “In a dream, a vision of the night,” about [Balaam’s] speaking with him at night. And similarly Elihou speaks about that which He had spoken with him at night. (Numb. 22:20, cont.) “If these men have come to invite you, arise and go with them”: From here you learn that in the way that a man wants to go, in it is he driven. As at first it was said to him (in Numb. 22:12), “Do not go with them.” As soon as he had become defiant, he went. As so is it written about him (in Numb. 22:22), “But God's anger was kindled because he was going.” The Holy One, blessed be He, said to him, “I do not desire the death of the wicked. [But] in as much as you want to be obliterated from the world, ‘arise and go with them.’” (Numb. 22:20, cont.), “But only the thing [that I tell you are you to do].” [These words are] to teach you that he went with a warning. Immediately he got up early in the morning [preparing his donkey] quickly all by himself. The Holy One, blessed be He, said to him, “You wicked man! Their ancestor Abraham has already anticipated you at the binding of his son Isaac,” as stated (in Gen. 22:3), “So Abraham arose early in the morning, saddled his he-ass.” (Numb. 22:21, cont.) “And went with the princes of Moab”: [These words are] to teach you that he was as glad at the tribulation of Israel as they were.

...And Avraham rose early in the morning, and saddled his donkey (Genesis 22:3). Rabbi Simeon b. Yohai said: Love upsets the natural order, and hate upsets the natural order. Love upsets the natural order: "And Avraham rose early in the morning, etc".: surely he had plenty of slaves? But the reason was that love upset the natural order. Hate upsets the natural order: "And Bilam rose up in the morning, and saddled his donkey" (Num. 22:21): surely he had plenty of slaves? Hate, however, upsets the natural order. Love upsets the natural order: "And Yosef made ready his chariot, etc." (Gen. 46:29): yet surely Yosef had plenty of slaves? But love upsets the natural order. Hate upsets the natural order: "And he made ready his chariot" (Ex. 14:6); yet surely he had plenty of slaves? Thus hate upsets the natural order. Rabbi Simeon b. Yohai said: Let saddling counteract saddling. Let the saddling done by our father Avraham in order to go and fulfill the will of the One at whose word the world came into existence counteract the saddling done by Bilam in order to go and curse Israel. Let preparing counteract preparing. Let Yosef’s preparing [of his chariot] to meet his father counteract Pharaoh’s preparing to go and pursue Israel. Rabbi Ishmael taught: Let the sword of the hand counteract the sword of the hand. Let the sword taken in the hand of our father Avraham, as it says, "And Avraham stretched forth his hand, and took the knife to slay his son" (Gen. 22:10), come and counteract the sword grasped by Pharaoh’s hand when he said, "I will draw my sword, my hand shall destroy them" (Ex. 15:9). "And took two of his young men with him, and Itzchak his son." (Gen. 22:3) Rabbi Abbahu said: Two people behaved with derech eretz (decency), Avraham and Saul: Avraham, as it says, "And took two of his young men with him"; Saul, as it says, "And Saul … went, he and two men with him" (I Sam. 28:8). "And he cleaved the wood for the burnt-offering," (Gen. 22:3) Rabbi Hiyya b. Rabbi Yosei said in the name of Rabbi Meyasha, and it was also repeated in the name of Rabbi Benaiah: As a reward for the two cleavings with which our father Avraham cleaved the wood of the burnt-offering, he earned that God should cleave [divide] the Sea before his descendants, as it says, And the waters were divided (Ex. 14:21). Said Rabbi Levi: Enough of this! In truth Avraham acted according to his powers an the Holy One of Blessing according to His powers. "And he rose up, and went to the place." (Gen. 22:3) Avraham was rewarded for rising up and for going.
