New Revised Standard Version
Therefore the Israelites are unable to stand before their enemies; they turn their backs to their enemies, because they have become a thing devoted for destruction themselves. I will be with you no more, unless you destroy the devoted things from among you.

Contemporary English Version

New American Bible
