King James Version
Therefore the children of Israel could not stand before their enemies, but turned their backs before their enemies, because they were accursed: neither will I be with you any more, except ye destroy the accursed from among you.English Standard Version
Therefore the people of Israel cannot stand before their enemies. They turn their backs before their enemies, because they have become devoted for destruction. I will be with you no more, unless you destroy the devoted things from among you.New International Version
That is why the Israelites cannot stand against their enemies; they turn their backs and run because they have been made liable to destruction. I will not be with you anymore unless you destroy whatever among you is devoted to destruction.
