KJV:
And the LORD sent an angel, which cut off all the mighty men of valour, and the leaders and captains in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he was come into the house of his god, they that came forth of his own bowels slew him there with the sword.
NASB:
And the LORD sent an angel who destroyed every mighty warrior, commander and officer in the camp of the king of Assyria. So he returned in shame to his own land. And when he had entered the temple of his god, some of his own children killed him there with the sword.
