Ephesians 6:14

stand firm, the belt of truth round your waist, let justice invest you like mail:

1 Thessalonians 5:8

but let us, who enjoy the light, be temperate; let us be arm'd with the breast-plate of faith and charity, and for an helmet, with the hope of salvation.

Revelation 9:17

the horses I saw in my vision had this appearance: the riders had breast-plates of fire, of jacinth, and brimstone: the heads of the horses were like the heads of lions; and out of their mouths issued fire, smoke, and brimstone.
