1 Samuel 19:5

for he put his life in his hand and struck the Philistine, and Yahweh worked a great victory for all Israel. You saw it and rejoiced. Why then will you sin against innocent blood, to kill David without a cause?”

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?
