Josh 6:18

וְרַק־אַתֶּם֙ שִׁמְר֣וּ מִן־הַחֵ֔רֶם פֶּֽן־תַּחֲרִ֖ימוּ וּלְקַחְתֶּ֣ם מִן־הַחֵ֑רֶם וְשַׂמְתֶּ֞ם אֶת־מַחֲנֵ֤ה יִשְׂרָאֵל֙ לְחֵ֔רֶם וַעֲכַרְתֶּ֖ם אוֹתֽוֹ׃

But keep away from the things devoted to destruction, lest you yourself be set apart for destruction. If you take any of these, you will set apart the camp of Israel for destruction and bring disaster upon it.
