Isaiah 19:2

And the three hundred blew the trumpets, and the LORD set every man’s sword against his fellow, even throughout all the host: and the host fled to Bethshittah in Zererath, and to the border of Abelmeholah, unto Tabbath.

And Saul and all the people that were with him assembled themselves, and they came to the battle: and, behold, every man’s sword was against his fellow, and there was a very great discomfiture.

And a man’s foes shall be they of his own household.

And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:

And I will call for a sword against him throughout all my mountains, saith the Lord GOD: every man’s sword shall be against his brother.

And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death.

Manasseh, Ephraim; and Ephraim, Manasseh: and they together shall be against Judah. For all this his anger is not turned away, but his hand is stretched out still.

Then God sent an evil spirit between Abimelech and the men of Shechem; and the men of Shechem dealt treacherously with Abimelech:

And the watchmen of Saul in Gibeah of Benjamin looked; and, behold, the multitude melted away, and they went on beating down one another.
