1 Samuel 25:31

then my lord will have no remorse or guilt of conscience over needless bloodshed and revenge. And when the LORD has dealt well with my lord, may you remember your servant.”

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.
