'Bloodguilt' in the Bible

So then, my lord, {as Yahweh lives and as your soul lives}, since Yahweh restrained you from bloodguilt {by taking matters into your own hand}, so then, may your enemies be like Nabal, even {those who seek to do my lord harm}.

And blessed be your discretion, and blessed be you who have prevented me this day from bloodguilt and [from] delivering myself by my own hand.
