This statement comes from 1 Kings 21. It refers to the incident involving Naboth’s Vineyard. King Ahab wanted a vineyard belonging to a man named Naboth, but Naboth refused to sell his ancestral inheritance.

Ahab's wife, Queen Jezebel, orchestrated a plot to have Naboth falsely accused of blasphemy and stoned to death so the King could take the land.

After Ahab went to take possession of the vineyard, God sent the Prophet Elijah to confront him. Elijah met him and delivered God's judgment, starting with the rhetorical question: "Have you killed and also taken possession?" (1 Kings 21:19).
