What does 1 Kings 22:38 mean?

They washed the chariot at a pool in Samaria, and the dogs licked up his blood, just as the prostitutes bathed there. This happened exactly as the Lord had said. 1 Kings 22:38 - Modern Text Bible

(The gruesome detail of dogs licking Ahab’s blood fulfills a previous prophecy, showing God’s word comes true even in small details.)
