Micah 4:13

Arise and thresh, O daughter of Zion, according to the Oriental custom of having the sheaves threshed out on the open threshing-floor with the aid of oxen; for I will make thine horn iron and I will make thy hoofs brass, giving to His people a new and unconquerable strength; and thou shall beat in pieces many people, not by victories of the flesh, but by those of the spirit; and I will consecrate their gain, what the enemies had gotten by robbery and plunder, unto the Lord, as devoted to Him, and their substance, all their possessions, unto the Lord of the whole earth, whom the heathen would eventually have to acknowledge as the one Ruler, even if they consistently refused to accept Him as the God of their salvation. Cf Philippians 2:11.
