"When David heard the news, he said, 'I swear by the LORD, who has delivered me out of every trouble, that the man who told me I had killed Saul, thinking he was bringing good news, I executed him.'" (2 Samuel 4:10)
Two brothers, leaders of raiding bands, kill Ish-bosheth while he is sleeping and bring his head to David: here is the head of Ish-bosheth, the son of Saul, your enemy. They expect reward. David's response is the mirror of his response to the Amalekite who killed Saul: When David heard the news, he said, 'I swear by the LORD, who has delivered me out of every trouble, that the man who told me I had killed Saul, thinking he was bringing good news, I executed him. How much more, when wicked men kill an innocent man in his own house and on his own bed, should I not now demand his blood from your hand and rid the earth of you!' He has them executed and their hands and feet cut off.
The consistency of David's response to political murder is remarkable: he refuses to benefit from violence done on his behalf, even when it removes his enemies. The Catechism identifies this principle as foundational to legitimate authority: the one who governs may not use murder as a tool of political advancement (CCC 2268).
Brothers and sisters, David refused to benefit from political murder three times: Saul, Abner, Ish-bosheth. Each time he acted consistently against his own short-term advantage. The leader whose principles hold under pressure is the leader whose authority is genuinely grounded in something beyond self-interest. What principles do you hold even when they cost you advantage?
Lord God, David refused to benefit from the deaths done in his interest. Give us the same principled consistency that holds even when the murder would benefit us. Through Christ our Lord. Amen.
