Micah 4:13

And thresh — The future strength of the church employed in subduing her enemies, is here foretold. Iron — This expresses the strength of the church firm as iron, to beat down her enemies. Brass — By this figurative speech, is the strength of Zion expressed, treading underfoot, and breaking the power of her enemies in pieces. And I — I, the church. Their gain — The spoils of my conquered enemies.
