Sanhedrin 105B

כרע נפל שכב וגו׳״.

he sunk, he fell, he lay” (Judges 5:27), which is interpreted as a reference to sex between Sisera and Jael.

״וידע דעת עליון״. השתא דעת בהמתו לא הוה ידע, דעת עליון הוה ידע? מאי דעת בהמתו? דאמרי ליה: מאי טעמא לא רכבת סוסיא? אמר להו: שדאי להו ברטיבא.

§ Balaam describes himself: “And he knows the knowledge of the Most High” (Numbers 24:16), and the Talmud asks: Now, if the knowledge of his animal he did not know, is it possible that the knowledge of the Most High he knew? The Talmud explains: What is the meaning of the knowledge of his animal? The princes accompanying him said to him: What is the reason that you did not ride horses? Balaam said to them: I brought the horses to graze in the pasture and rest there.

אמרה ליה: ״הלא אנכי אתנך״! לטעינא בעלמא. ״אשר רכבת עלי״! אקראי בעלמא. ״מעודך עד היום הזה״!

The donkey said to him: “Am I not your donkey” (Numbers 22:30)? Balaam said to the donkey: Merely for burdens, not for riding. The donkey said to him: “Upon which you have ridden” (Numbers 22:30). Balaam said to the donkey: That was mere happenstance and is not a regular occurrence. The donkey said to him: “Your whole life until this day” (Numbers 22:30).

ולא עוד, אלא שאני עושה [לך] מעשה אישות בלילה. כתיב הכא: ״ההסכן הסכנתי״, וכתיב התם: ״ותהי לו סכנת״.

The donkey continued: Moreover, I perform a conjugal act for you and we engage in bestiality at night. From where is this derived? It is written here: “Was I ever wont [hahasken hiskanti] to do so to you” (Numbers 22:30)? And it is written there with regard to Abishag the Shunammite: “And let her be a companion [sokhenet] to him” (I Kings 1:2). Just as the root samekh, kaf, nun indicates sex in the case of Abishag, the same is true with regard to the donkey. Balaam was unable to best his donkey in a debate.
