house divided against itself cannot stand

The phrase "house divided against itself cannot stand" originated from a passage in the New Testament of the Bible. It was spoken by Jesus in response to the Pharisees' accusation that he was casting out demons by the power of Satan. In the context of the Bible, it refers to the idea that if a family or group is in conflict and divided, it will ultimately lead to its downfall. The phrase is often used more broadly to describe any situation where internal conflicts and divisions weaken or destroy an entity or organization.
