Joshua 6:17

6:17 And the city shall be accursed, [even] it, and all that [are] therein, to the LORD: only Rahab the harlot shall live, she and all that [are] with her in the house, because she hid the messengers that we sent.

Joshua 7:13

7:13 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.
