Or HaChaim on Deuteronomy 33:11/אור החיים על דברים ל״ג:י״א

1 ומשנאיו מן יקומון. "and let his enemies rise no more." The unusual construction מן יקומון may be a reference to the kingdom of the Greeks which would fall victim to the Hasmoneans (members of the tribe of Levi; compare Bamidbar Rabbah 14). Moses prayed that the Levites be able to maintain themselves even during the period when the Greeks (or other nations) would generally oppress the Jewish people. The plural משנאיו is a reference to a time when the Jews would be oppressed in their homeland and appear helpless. Even at such a time, מחץ מתנים, the Hasmoneans would smite their oppressors.
