Thine hand shall be lifted up upon thine adversaries, and all thine enemies shall be cut off.

Wesley's Notes

5:9 Thine hand - Thou people of God.

Jamieson-Fausset-Brown Bible Commentary

9. Thine hand shall be lifted up-In Isa 26:11 it is Jehovah's hand that is lifted up; here Israel's as Mic 5:8 implies, just as "Zion" is addressed and directed to "beat in pieces many people" (Mic 4:13; compare Isa 54:15, 17). For Israel's foes are Jehovah's foes. When her hand is said to be lifted up, it is Jehovah's hand that strikes the foe by her (compare Ex 13:9, with Ex 14:8).

Matthew Henry's Concise Commentary

5:7-15 The remnant of Israel, converted to Christ in the primitive times, were among many nations as the drops of dew, and were made instruments in calling a large increase of spiritual worshippers. But to those who neglected or opposed this salvation, they would, as lions, cause terror, their doctrine condemning them. The Lord also declares that he would cause not only the reformation of the Jews, but the purification of the Christian church. In like manner shall we be assured of victory in our personal conflicts, as we simply depend upon the Lord our salvation, worship him, and serve him with diligence.
