I Samuel 25:30-31

And it shall come to pass, when the LORD has done for my lord according to all the good that He has spoken concerning you, and has appointed you ruler over Israel, that this will be no grief to you, nor offense of heart to my lord, either that you have shed blood without cause, or that my lord has avenged himself. But when the LORD has dealt well with my lord, then remember your maidservant.”
