When they grasped you with their hands, you splintered and you tore open their shoulders; when they leaned on you, you broke and their backs were wrenched.
NIV
When they grasped you with the hand and leaned upon you, you broke and tore their whole shoulder, and [by injuring their muscles made them so stiff and rigid that] they could do no more than stand.
AMP
When they took hold of thee by thy hand, thou didst break, and rend all their shoulder: and when they leaned upon thee, thou brakest, and madest all their loins to be at a stand.
KJV
