§ 02 · King James Bible
1 Samuel 19:5
For he did put his life in his hand, and slew the Philistine, and the LORD wrought a great salvation for all Israel: thou sawest it, and didst rejoice: wherefore then wilt thou sin against innocent blood, to slay David without a cause?
Simple English
He risked his life to kill the Philistine and God saved everyone. You saw this and were happy. So why would you let someone wrongly kill David, who is innocent?
