1 Samuel

1. 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?
2. 1 Samuel 25:31
   That this shall be no grief unto thee, nor offence of heart unto my lord, either that thou hast shed blood causeless, or that my lord hath avenged himself: but when the Lord shall have dealt well with my lord, then remember thine handmaid.
