Your cords hang loose; they cannot hold the mast firm in its place or keep the sail spread out. Then prey and spoil in abundance will be divided; even the lame will take the prey.
Isaiah 33:23

This is referring to the Assyrians who were unable to stand against the power of YHVH and who are despoiled by the weakest of Israel. Under our own power, we would never be sufficient to stand against the Adversary, but with God on our side, who can stand against us?
