Ibn Ezra on Numbers 23:24

הן עם כלביא יקום. רמז כי ינצח מלכי כנען והקרוב אל הדעת הדבר הקרוב כמו מלחמת מדין שלא נשמע מלחמה כמוה שלא נפקד מזרע ישראל אחד ומתו חמשה מלכים ונפש אדם אשר לא ידעו משכב זכר היו שלשים ושתים אלף: BEHOLD A PEOPLE THAT RISETH UP AS A LIONESS. This hints that Israel will conquer the kings of Canaan. It seems most logical to interpret it this way regarding a soon-to-occur event,⁹⁶That it relates to a war that occurred prior to the conquest of Canaan. such as the war against Midian.⁹⁷See Num. 31:1-12. A war like it was unprecedented. No Israelites were lost in this war⁹⁸See Num. 31:49. and five kings died in it,⁹⁹Num. 31:8. along with thirty-two thousand females who never slept with a man.¹⁰⁰Num. 31:35.

ודם חללים. המלקוח ואת כל חילם ועל דרך הדרש לא ישכב משה עד יאכל טרף כן כתוב אחר תאסף אל עמך: AND DRINK THE BLOOD OF THE SLAIN. The spoil and all their wealth.¹⁰¹The wealth of the slain. See Num. 31:11. According to the midrashic interpretation it means that Moses would not die until he ate of the prey.¹⁰²Moses wouldn’t die until he first defeated and looted the Midianites. Scripture similarly reads: Afterward shalt thou be gathered unto thy people (Num. 31:2).
