The Ir nidachat (Hebrew: עיר נידחת; the "city led astray") is a biblical command on idolatry in Deuteronomy 13:13-19. If the inhabitants of an Israelite city become idolaters, they and their livestock must be slaughtered and the city be burnt to the ground, never to be rebuilt. See discussion under Re'eh, the weekly Torah portion including this section.
