Albert Barnes Commentary Micah 5:9

"Let thy hand be lifted up above thine adversaries, and let all thine enemies be cut off." — Micah 5:9 (ASV)

Their hand shall be lifted up upon their adversaries - The might of the Church is the Might of Christ in her, and the glory of the Church is His from whom it comes and to whom it returns. It is all one, whether this is said to Christ or to the “remnant of Jacob,” that is, His Church.

Her “enemies” are His, and hers only because they are His, and hate her as belonging to Him. They “shall be cut off,” either ceasing to be His enemies, or ceasing to be, as Julian or Arius or antichrist, “whom the Lord shall consume with the spirit of His Mouth and shall destroy with the brightness of His Coming” (2 Thessalonians 2:8).

And in the end, Satan also, over whom Christ gave the Apostles “power to tread on all the power of the Enemy” (Luke 10:19), shall be “bruised under our feet” (Romans 16:20).
