'Chest' in the Bible

“But the tax collector, standing far off, would not even raise his eyes to heaven but kept striking his chest and saying, ‘God, turn Your wrath from me—a sinner!’

Stand, therefore,with truth like a belt around your waist,righteousness like armor on your chest,

and among the lampstands was One like the Son of Man, dressed in a long robe and with a gold sash wrapped around His chest.
