'Gird' in the Bible

Then he said to Gehazi, “Gird up your loins and take my staff in your hand, and go your way; if you meet any man, do not salute him, and if anyone salutes you, do not answer him; and lay my staff on the lad’s face.”

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