1. That I might smite or behead them. Or,
2. That I might put my yoke upon their necks, or bring them into subjection. Or rather thus, Thou hast made them turn their backs to me, i.e. flee away from me; for so this very phrase is used and rendered, Exodus 23:27 Joshua 7:8,12, and elsewhere. So far are they mistaken, that say this Hebrew word oreph is only used for the neck, and not for the back. That I might destroy them; that I might have opportunity to destroy them.
