1 Samuel 25:30-31

And it will happen when the LORD does for my lord according to all the good that He has spoken (promised) concerning you, and appoints you ruler over Israel, that this [incident] will not cause grief or [bring] a troubled conscience to my lord, both by having shed blood without cause and by my lord having avenged himself. When the LORD deals well with my lord, then remember [with favor] your maidservant.”
