"Gird up now thy loins like a man; for I will demand of thee, and answer thou me."
The above passage from Job 38:3 is just one of several references in the Bible to "girding up one's loins" -- a directive that may have made sense to an ancient audience but which eludes us today.
The simple reason for misunderstanding is fashion. Men and women in the Biblical era typically wore tunics, which would have understandably gotten in the way whenever a man needed to run, fight or perform hard labor -- as men are wont to do, of course.
Men got around this issue by fastening a girdle to their waist and tucking the loose ends of the tunic into it, thus "girding up their loins." Artist Ted Slampyak created a step-by-step guide for The Art of Manliness that explains how to accomplish this Biblically-manly act.
