2 Kings 14:5

And it came to pass, as soon as the kingdom was strengthened in his hand,.... That he was well settled on the throne, and had a share in the affection of the people, and the idolatry and murder his father had committed were worn off of the minds of the people, and the friends of the conspirators against him were become few or none:

that he slew his servants that had slain the king his father; charged them with the murder in a court of judicature, obtained a sentence against them, and had them executed.
