'Loins' in the Bible

And they answered him, He was a hairy man, and girt with a girdle of leather about his loins. And he said, It is Elijah the Tishbite.

Then he said to Gehazi, Gird up thy loins, and take my staff in thy hand, and go thy way: if thou meet any man, salute him not; and if any salute thee, answer him not again: and lay my staff upon the face of the child.

And Elisha the prophet called one of the sons of the prophets, and said unto him, Gird up thy loins, and take this vial of oil in thy hand, and go to Ramoth-gilead.
