Job 19:24; Job 20:24; Job 28:2; Job 41:27

24 That they were graven with an iron pen and lead in the rock for ever!

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

2 Iron is taken out of the earth, and brass is molten out of the stone.

27 He esteemeth iron as straw, and brass as rotten wood.
