Yahweh appears to Elijah about the death of Naboth (1 Kings 21:17-21:19)

“Then the word of Yahweh came to Elijah the Tishbite, saying. ‘Go down to meet King Ahab of Israel, who rules in Samaria. He is in the vineyard of Naboth, where he has gone to take possession of it. You shall say to him. ‘Thus says Yahweh. Have you killed Naboth and also taken his possession?’ You shall say to him. ‘Thus says Yahweh. In the place where dogs licked up the blood of Naboth, dogs will also lick your own blood.’”

Elijah and King Ahab have already have had some encounters. Yahweh spoke directly to Elijah. He told him that King Ahab was taking possession of the vineyard of Naboth. There was a double statement for King Ahab. First, he has killed Naboth and taken his possession. Second, dogs will lick his blood when he dies in the same spot as Naboth. This is a difficult message for Elijah to deliver to the king
