1 Samuel 25:25-26

25Please do not let my lord pay attention to this worthless man, Nabal, for as his name is, so is he. Nabal (fool) is his name and foolishness (stupidity) is with him; but I your maidservant did not see my lord’s young men whom you sent.

26So now, my lord, as the Lord lives, and as your soul lives, since the Lord has prevented you from shedding blood, and from avenging yourself by your own hand, now then let your enemies and those who seek to do evil to my lord, be as [self-destructive as] Nabal.
