2 Samuel 7:28-29

“And now, O Lord God, You are God, and Your words are true, and You have promised this goodness to Your servant.
Now therefore, let it please You to bless the house of Your servant, that it may continue before You forever; for You, O Lord God, have spoken it, and with Your blessing let the house of Your servant be blessed forever.”
