'Executing' in the Bible

and I have brought in on you a sword, executing the vengeance of a covenant; and ye have been gathered unto your cities, and I have sent pestilence into your midst, and ye have been given into the hand of an enemy.

And it cometh to pass, in Jehu's executing judgment with the house of Ahab, that he findeth the heads of Judah and sons of the brethren of Ahaziah, ministers of Ahaziah, and slayeth them.
