Circular swelling, mid-part of a shield.
The wicked man travaileth with pain all his days, and the number of years is hidden to the oppressor. Trouble and anguish shall make him afraid; they shall prevail against him, as a king ready to the battle. For he stretcheth out his hand against God, and strengtheneth himself against the Almighty. He runneth upon him, even on his neck, upon the thick BOSSES of his bucklers: because he covereth his face with his fatness, and maketh collops of fat on his flanks. ( Job 15:27)
