'Accursed' in the Bible

But as for you, keep yourselves [away] from the things under the ban [which are to be destroyed], so that you do not covet them and take some of the things under the ban [for personal gain], and put the camp of Israel under the ban (doomed to destruction), and bring disaster upon it.

That is why the soldiers of Israel could not stand [and defend themselves] before their enemies; they turned their backs [and ran] before them, because they have become accursed. I will not be with you anymore unless you destroy the things under the ban from among you.

Rise up! Consecrate the people and say, ‘Consecrate yourselves for tomorrow, for thus says the Lord, the God of Israel: “There are things under the ban among you, O Israel. You cannot stand [victorious] before your enemies until you remove the things under the ban from among you.”

Did not Achan the son of Zerah act unfaithfully in the things under the ban, and [as a result God’s] wrath came on the entire congregation of Israel? And that man did not perish alone in his wrongdoing.’”
