Hip and thigh; upon their hips and thighs, peradventure not designing to kill them, but to make them incapable of military employment, or of doing hurt to the Israelites. Or, He smote them with his leg upon their thigh, i.e. without any other weapon but his leg and foot he kicked them, and made them lame and useless for war. With a great slaughter, Heb. with a great stroke; for so it was, even to them whom it did not kill. He dwelt in the top of the rock Etam; partly because there he could better defend himself from his enemies; and partly because he would not involve his brethren in the same danger with himself, but, like a worthy magistrate, would secure them even with his own greater hazard.
