'Loins' in the Bible

And I saw [something] like [the] outward appearance of amber, [something] like [the] appearance of fire, [with] a covering around [it], from the likeness of his loins and {upward}. And from the likeness of his loins and {downward} I saw [something] like [the] appearance of fire, and {it was radiant all around}.

When they took hold of you with the hand, you snapped, and you split their every shoulder. And when they leaned on you, you broke, and you caused all of their loins to wobble."
