'Steel' in the Bible

He teacheth my hands to war; so that a bow of steel is broken by mine arms.

He shall flee from the iron weapon, and the bow of steel shall strike him through.

He teacheth my hands to war, so that a bow of steel is broken by mine arms.

Shall iron break the northern iron and the steel?

The shield of his mighty men is made red, the valiant men are in scarlet: the chariots glitter with the sheen of steel, in the day of his preparation, and the spears are brandished.

The chariots race madly in the streets;They rush wildly in the broad plazas.Their appearance is like torches;They rush in various directions like forked lightning.
