'Executing' in the Bible

Yahweh said to Jehu, "Because you have done well in executing that which is right in my eyes, [and] have done to the house of Ahab according to all that was in my heart, your sons of the fourth generation shall sit on the throne of Israel."

It happened, when Jehu was executing judgment on the house of Ahab, that he found the princes of Judah, and the sons of the brothers of Ahaziah, ministering to Ahaziah, and killed them.
