'Armor' in the Bible

But the king of Israel replied, "Tell him, "The one who is starting to strap on his battle armor should never brag like the one who is taking it off.'"

Meanwhile, somebody drew his bow aimlessly and struck the king of Israel between the scales where his armor breastplates joined, so he instructed his chariot driver, "Turn around and take me out of the battle, because I've been severely wounded."
