The girdle was a band about six inches wide that had fasteners in front. It was worn around the loins (the midsection of the body between the lower ribs and the hips). Gird up your mind or gird up your heart are examples of variants of this phrase and call for mental or spiritual preparation for a coming challenge.gird up your loins like a man,

And I will ask you, and you instruct Me!
