'Loins' in the Bible

They answered him, “He was a hairy man with a [wide] leather band bound around his loins.” And Ahaziah said, “It is Elijah the Tishbite.”

Then he said to Gehazi, “Gird up your loins (prepare now!) and take my staff in your hand, and go [to the woman’s house]; if you meet any man [along the way], do not greet him and if a man greets you, do not [stop to] answer him; and lay my staff on the face of the boy [as soon as you reach the house].”

Now Elisha the prophet called one of the sons of the prophets and said to him, “Gird up your loins (prepare for action), take this flask of oil in your hand and go to Ramoth-gilead.
