Kabbalah do Samuela II 12:5

Dumah said, Master of the universe, I have one thing against him! He opened his mouth and said, "as Hashem lives, the man that has done this deserves to die" (Ibid. 5). So he has condemned himself to death, and therefore I have the power over him. He said to Dumah, You have no permission, because he has already confessed in front of Me saying, 'I have sinned against Hashem' even though he did not sin. Although his sin against Uriah was (by killing him), I have written his punishment and he has accepted it! Immediately Dumah returned to his place, disappointed.
