Rashi on Numbers 23:24/רש"י על במדבר כ״ג:כ״ד

1הן עם כלביא יקום וגו׳ BEHOLD, THE PEOPLE RISES AS A LIONESS, etc. — When they rise from their sleep in the morning they show themselves strong as a lioness and as a lion to “snatch at” the Divine precepts (to perform them immediately) — to clothe themselves with the Tallith, to read the Shema and to lay Tephillin (cf. Midrash Tanchuma, Balak 14).

2לא ישכב HE LIES NOT DOWN at night on his bed until he consumes (עד יאכל) and destroys every noxious thing which comes to prey upon him (טרף). How so? He reads the Shema at his bedside and commends his spirit into the hands of the Omnipresent (Midrash Tanchuma, Balak 14). If a camp or troop comes to injure them, the Holy One, blessed be He, protects them and fights their battles and causes them (the enemies) to fall slain (חללים).— Another explanation of הן עם כלביא יקום is as the Targum has it (“Behold the people shall dwell as a lioness and as a lion shall he raise himself; he will not dwell in his land until he hath slaughtered and he will inherit the wealth of the peoples”).

3ודם חללים ישתה AND HE SHALL DRINK THE BLOOD OF THE SLAIN — He unwittingly foretold the future — that Moses would not die until he will have made the kings of Midean fall slain (חללים) and he (Balaam) will have been slain with them, — as it is said, (Joshua 13:22) “And Balaam the son of Beor, the soothsayer, did the children of Israel slay with the sword among the rest of their slain (חלליהם)" (cf. Midrash Tanchuma, Balak 14).
