'Breastplates' in the Bible

And Uzziah prepared small shields, spears, helmets, breastplates, bows, and slingstones for the whole army.

From that day, half of my servants were working on craftsmanship, half were holding spears, small shields, bows, and breastplates. The commanders were behind the whole house of Judah.

and they had breastplates like iron breastplates, and the sound of their wings [was] like the sound of many {horse-drawn chariots} running into battle.

And in this way I saw the horses in the vision, and those seated on them, who had fiery [red] and hyacinth-colored and sulphurous [yellow] breastplates, and the heads of the horses [were] like the heads of lions, and out of their mouths came fire and smoke and sulphur.
