Sforno on Numbers 24:8/ספורנו על במדבר כ״ד:ח׳

1יאכל גויים צריו, a promise that will be fulfilled in the distant future. Moses repeats this in Deuteronomy 32,43 ונקם ישיב לצריו, “G’d will take vengeance on their oppressors.”

2וחציו ימחץ, again words paraphrased by Moses in Deuteronomy 32,42. אשכיר חצי מדם “I will make My arrows drunk with blood.”
