Could I ask what "gird your loins" means?

To 'gird your loins' means for someone to "prepare to do something difficult or dangerous". The phrase's origin dates back to the Biblical era when people wore tunics. Whenever someone needed to run, fight or perform hard labor they would fasten a girdle to their waist and tuck the loose ends of the tunic into it, thus 'girding up their loins'.
