A land wherein thou shalt eat bread without scarceness, thou shalt not lack any thing in it; a land whose stones are iron, and out of whose hills thou mayest dig brass.
Deuteronomy 28:23
And thy heaven that is over thy head shall be brass, and the earth that is under thee shall be iron.
Deuteronomy 33:25
Thy shoes shall be iron and brass; and as thy days, so shall thy strength be.
