Breastplate

And thou shalt take the garments, and put upon Aaron the coat, and the robe of the ephod, and the ephod, and the breastplate, and gird him with the curious girdle of the ephod:

For he put on righteousness as a breastplate, and an helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloke.

Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;

But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.
