Killing Commanded and Sanctioned
Thus saith the Lord God of Israel, Put every man his sword by his side, and go in and out from gate to gate throughout the camp, and slay every man his brother, and every man his companion, and every man his neighbor. (Ex. 32: 27.)
So Jehu slew all that remained of the house of Ahab.... And the Lord said unto Jehu, Because thou hast done well in executing that which is right in mine eyes, and hast done unto the house of Ahab according to all that was in my heart, thy children of the fourth generation shall sit on the throne of Israel. (2 Kings 10: 11, 30.)
