Hip

(shoq, "leg," "limb," "hip," "shoulder"):

Samson smote the Philistines "hip and thigh" (Hebrew "leg upon thigh"), which was indicative of "a great slaughter" (Judges 15:8), the bodies being hewed in pieces with such violence that they lay in bloody confusion, their limbs piled up on one another in great heaps.
