'Exercise' in the Bible

Then his wife Jezebel said to him, “Now, exercise your royal power over Israel. Get up, eat some food, and be happy. For I will give you the vineyard of Naboth the Jezreelite.”

Then Jehu looked for Ahaziah, and Jehu’s soldiers captured him (he was hiding in Samaria). So they brought Ahaziah to Jehu, and they killed him. The soldiers buried him, for they said, “He is the grandson of Jehoshaphat who sought the Lord with all his heart.” So no one from the house of Ahaziah had the strength to rule the kingdom.
