Isaiah
King James Version (KJV)

“And righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins.”
King James Version (KJV)
11:5 The girdle - It shall adorn him, and be the glory of his government, as a girdle was used for an ornament, #Isa 3:24|, and as an ensign of power, #Job 12:18|, and it shall constantly cleave to him in all his administrations, as a girdle cleaveth to a man's loins.
