'Brazen' in the Bible

For, behold, I have made thee this day a fortified city, and an iron pillar, and brazen walls, against the whole land, against the kings of Judah, against the princes thereof, against the priests thereof, and against the people of the land.

And I will make thee unto this people a fortified brazen wall; and they shall fight against thee, but they shall not prevail against thee; for I am with thee to save thee and to deliver thee, saith Jehovah.

And the pillars of brass that were in the house of Jehovah, and the bases and the brazen sea that were in the house of Jehovah, did the Chaldeans break in pieces, and carried all the brass of them to Babylon.

The two pillars, the one sea, and the twelve brazen bulls that were under the bases, which king Solomon had made for the house of Jehovah-the brass of all these vessels was without weight.
