Up, sanctify (set apart for a holy purpose) the people, and say, Sanctify yourselves for tomorrow; for thus says the Lord, the God of Israel: There are accursed things in the midst of you, O Israel. You can not stand before your enemies until you take away from among you the things devoted [to destruction]. (AMP)
Up, sanctify the people, and say, Sanctify yourselves against to morrow: for thus saith the LORD God of Israel, There is an accursed thing in the midst of thee, O Israel: thou canst not stand before thine enemies, until ye take away the accursed thing from among you. (KJV)
