'Loins' in the Bible

He looseth the bond of kings, And he bindeth their loins with a girdle.

Because he hath covered his face with his fatness, And gathered fat upon his loins;

If his loins have not blessed me, And if he hath not been warmed with the fleece of my sheep;

Gird up now thy loins like a man; For I will demand of thee, and declare thou unto me.

Gird up thy loins now like a man: I will demand of thee, and declare thou unto me.

Lo now, his strength is in his loins, And his force is in the muscles of his belly.
